I'm afraid Steve Huffman made the correct calculation that Reddit's network effect is large enough that the wound it'll sustain with the API lockout won't be enough to imperil the platform.
On the scale of other platform enshittification (Digg in particular), this one isn't directly user-hostile enough, and the aren't any good enough alternatives.
Enshittification is basically inevitable for (venture)capitalist-funded online platforms. My biggest disappointment is that Reddit went that venture-capitalist (or adjacent, whatever) route, I thought/hoped their "Reddit Gold" approach was good enough to be sustainable.
