You say that, but what if they choose paternalistic restrictions on post frequency? "You must make all your choices yourself, and you must prefer that!" <- doesn't actually seem all that free, to me. People act like any one website must support all use cases, all the time, when in reality, opting in to the site is also a choice; literally nothing on the Internet is required, you can choose not to participate (and all of the consequences, good or bad, that come with that choice).
