It seems to me that users should _want_ their community platform to be profitable in order to sustain, but not "too profitable" (=greed) or the sense of community vanishes.
If that is true, is it the responsibility of the online citizen to interact/transact on a platform with the "right" degree of profitability (not too small, or it'll close tomorrow, but also not to greedy, or enshittification occurs)?
PS: How profitable exactly is "right" - reminds me of the family game where the winner is the "most average" person - scoring points closest to the arithmetic mean instead of the person with the max. score.
Enshittification is a direct consequence of this mindset being applied to companies who reach something resembling market saturation. Once your user growth starts slowing down, you need to show that you'll continuously make more money per user than you did before. And that path can only lead to shit.
Maybe Ycomb has done some math, possibly a litte more up to date, and the people, culture and cred this site gives them is worth more than selling it?
Your main point remains valid of course, but we don't all suffer evenly - the internet is still a great place for many and a new home will be found or at least the next generation will find one.
