I don't understand what you're asking, exactly. I didn't say he wasn't allowed, but you're going to get a lot of attention for purging popular things, attention that you don't get if you simply cut back to being "less Online" and shift from huge amounts of time to fifteen minutes a week making an occasional comment and replying to the occasional direct message.
(That said, all this chasing and doxing of this poor guy really is disgusting. If nothing else he absolutely has the right to leave and stop actively hosting things he doesn't want to host anymore.)

But people usually leave farewell notes. Or a will.
Because people were using it, and depending on it.
