Rodger Ebert doesn't have to be an award winning dictator to say when a movie is bad. You don't have to be a five star chef to say a meal is shit.
		
		
	 
Or, as I like to say, "I don't have to be an aerospace engineer to point out that there's a hole in the side of the plane."
However, the rest of your analogy doesn't hold water.  Full disclosure; I've been a game developer for about twelve years and worked at both indie startups and big-name companies that developed some of the most well-known games of all time.
	
	
		
		
			These problems are the same problems that there are in the game industry. The market complains about how everyone and their mother are trying to make the next Call of Duty. Some people have started their own indie companies to make innovative games; however, just because I say something like, "Battlefield 3 is ass, EA should stop beating the series dry." Doesn't mean I need to start writing code and modeling characters. Why do these games keep getting made? They make money, and if a company is in the game to make money, that's what safe.
		
		
	 
No one is actually saying you're not allowed to complain or criticize a company's products or direction.  If you did in fact say "hey, EA should stop making more Battlefields", no one is going to tell you you don't have a right to say that.  They might helpfully point out that if you don't want to keep playing Battlefield, you should check out any of the hundreds of other games by any of the hundreds of other companies out there, but they're not going to tell you that if you don't like EA's focus, to go make your own game.  Although they might question why you insist on buying Battlefield year after year if you don't like it, just so you can keep giving EA your business despite you not liking their product.
If, however, you said "EA should stop making Battlefield games, OMG are their designers so stupid that they can't come up with new ideas?  I had five new ideas for games this morning alone!  EA should hire me!", then I'd call you an idiot.
And, when I was done calling you an idiot, I might helpfully explain that every company solicits game ideas from its employees all the time, not just the designers.  I personally wrote at least three game pitches during my stint in the industry for different companies.  All of them got great feedback from the higher-ups.  One even got greenlit for development, but for various reasons it was never made (mostly due to that particular branch of the company being closed down).
There is no shortage of ideas in the gaming industry.  But, as you yourself noted, for various reasons companies evaluate them and (often) reject them as not being viable.  Sometimes, they may just be ahead of their time; folks were pitching ideas for deformable landscape games for years, but the tech just wasn't there for anything more complex than Worms.  So, calling companies idiots/incompetent for not being able to come up with new ideas is way off-base.
A more personal example; I published a game I wrote myself on the Android marketplace a few months ago.  The art's a bit lacking, because I had to do it myself and I'm not an artist.  If you wrote to me and said "Hey Phineas, your game's art is lacking," I'd agree with you and promise to do better next time.  If you wrote to me and said "Hey Phineas, your game's art sucks!  What, were you too lazy and/or cheap to hire an artist?", I'd inform you that I went through five different artists and that none of them were able to deliver, which forced me to do the art myself.  At that point, if you called me a liar and told me that I was just too lazy to do it, I'd then tell you to either find me an artist or go fuck yourself.
As an aside, I think that's the point we're at with the tickling video industry; producers are tired of fielding complaints that their models are "faking" no matter what kind of reactions the girl has, so they're just telling you to go fuck yourself.
So, this thread.  The OP was my second example; he was calling out producers for being lazy and deliberately refusing/being too incompetent to try new things.  Why, he thought of fifty new scenarios by lunchtime, by Cracky, surely the pros could come up with 
one?
Well, again, of course most of the better producers come up with new scenarios all the time.  For whatever reason, though, they don't shoot them.  But that of course just means that said producer is just lazy and stupid, right?  Not that their sales figures show that doing such a video would be a big risk for little gain.
But the risk is worth it, you say?  The OP seems to think so.  He seems to think that his ideas are so good, that producers need to hire him as a consultant to set them straight.  His ideas are gold!  So the producers say "okay, if you're that confident in your ideas, prove us all wrong.  Shoot them and put us all out of business."
Oh, but he doesn't want to do 
that.  That has the chance to fail, and make him look stupid.  No, he wants 
them to put up the money to hire 
him - which, conveniently, puts him in a no-lose situation.  After all, if his video ideas flop, it's not he who loses out; he got his consultant's fee, it's the producer who loses out... both for paying for his lousy idea and sinking money into shooting it.
And that's the problem; by demanding to be hired as a consultant, he's implying that he can do a better job than the producers, but he doesn't want to take that risk.  He wants someone else to do the heavy lifting while he profits, and it's pretty easy to talk a big game when it's someone else's money on the line.
So by all means, complain, if you feel you have a valid point to make; after all, if the plane has a hole in it, tell somebody.  But, if instead you imply that you can do a better job, then do it.  If you say you can make a better game than EA, then yeah, we're gonna tell you to get coding.  If you tell Tickle Inc. that Polly Pedicures was their best model of all time and why the fuck did they only hire her for one video, are they stupid or something?, and they come back and tell you that Polly's videos sold exactly two copies and they couldn't afford to buy her a Happy Meal, let alone pay her for another shoot, then you're the idiot, not the producer.   If you then tell them that the fans really loved her and they should give a little back and give the fans what they want even if it didn't make a lot of money, they'd be well within their rights to tell you that it's easy to say that when it's not your money paying her fees and that if you really want to see her again, prove that her videos will turn a profit by buying them.
Fun fact: When I was in college, I thought like the OP.  I thought if the industry just hired me I could put all my great ideas into great games and revolutionize the industry.  In some ways, I was right.  But in a lot of ways, I was wrong.  Time and experience with what I was criticizing proved that.
