Control is subjective. To the degree you accept that there should be terms and conditions to speech. To go further, i also mean control over the platform and how people access it. Closing off api access charging a zillion dollars to use it externally, then blocking privacy enhancing tools requiring logins etc. You must follow their terms and conditions in order to chat with communities online.
It's not reddit that's broken and has been from the beginning. They succeeded in a capture technique. They should have always charged for their API access, they should have always required authentication and logging. But they only did it once the majority of online community discussion moved to reddit.
To be clear there have been more events that cause reddit to tighten controls on speech. Wall street bets temporary lock is the first on that comes to mind. To say that anyone's online speech is regulated by a single companies terms and conditions _is_ control. When people hosted forums and other community boards, did they have rules, yeah of course, we still see that with mastodon now, but to say that is the same control is not an honest review.
