While the "recent troubles" put energy to my leaving, I have always been uncomfortable with Reddit, Twitter, Discord, Stack Overflow, Quora and Fandom, as corporate-owned repositories who work by, in one way or other, profiting off of freely contributed work.
It used to be that if someone wanted to help people with freely-given information, they'd offer it in a forum, on Usenet, or on a website they started and hosted themselves, or if it fit in there, put it on Wikipedia. Now, people add it to a freaking pile that corporations monetize. Don't just hand them value! Put it somewhere that won't beg you to install an app, or beg you to "upgrade" to "Nitro," or force you to watch intrusive ads, or force people to create an account to see it, or track you! Your volunteer labor should not be a profit center!
Forums and websites have always used content to market things (think DAU or visitors to sell more expensive banner ads at the top of a post).
I agree that forum hosts were (mostly) random people that wanted to do something for their community, but monetization didn't kill the friendly Internet, consolidation did.
