I try to remind myself that many people are from different countries, and politics are often quite different in other places, but at least from a USA perspective, any "new puritanism" type behavior is almost overwhelmingly conservative, and it is the progressives who fight against it. You know... the so-called "snowflakes" that conservatives like to tell what not to do because it's not how things were in "the good ol' days." Sure, there's conversations about "safe spaces" and "microaggressions" and such, but I don't know any progressives who are heavily into outright banning anything, except perhaps when it comes to Nazi propaganda. (Can't say I tolerate that myself, actually.) Certainly not sexual freedom of expression.
Now. Tumblr. As I have seen so far, that is TRULY a capitalist thing. It's about, as was said by several others here, mismanaging the site, permitting illegal activity via spambots, and not doing anything about it (or enough about it) until it hit them in their pocketbooks, after which they took a radical approach to trying to fix what was never the actual problem by using the same methods that didn't work well the first time. That's pretty much it. No parties, no social movements, nothing to get excited about except for the good old bottom line. And that is probably what's saddest about it all.
I hope it changes. Niche groups, especially fetish, LGBT+, women's interests and sex workers of all varieties found a good place on Tumblr, and that now has a very good chance of changing. It's too bad. But it's not about progressives ruining anything.
