In 2009, I (along with a team of developers) built a Twitter client. Ultimately, it was -- and it's still used -- by millions of people.
When Twitter closed it's API to 3rd parties, we were the one excepted from this.
So yeah, I've monetarily benefitted from Twitter's existence. I must absolutely admit that.
And so for very personal reasons, I didn't want to give up my Twitter account -- even as I know they're partially responsible for the rise of Fascism.
