The thing he really talks about caring about is preventing LLMs from getting his data and using it to provide answers that reduce traffic to Reddit. Except LLMs weren't purely trained on Reddit, and the high majority of the internet where the training data did come from doesn't have a convenient API... so that makes it a little harder, I guess, but it really has no effect.

Then other times, he complains about the advertising revenue, but contradicts himself and says actually the 3rd party app userbase is 3% of all users and inconsequential but people just want to bandwagon the poor multi-hundred million dollar company. Yet it's such a big opportunity cost that can't be ignored and there's just no better way.
