My guess is that the changes will still go ahead and the general quality of content on reddit will go down longer term although how much is an open question.

AI is going to do a shitty job identifying AI, so all of your datasets are going to get worse and worse. I could imagine a bunch of generative AI bots just melting down every message board on the planet to the point where you have to stop training on recent data.
I was hoping for the bots to export their existential crisis' to the rest of the web. Bots producing a loop, where they train on the data that they produce, would create some insane results.
If the communities will be gone for good (not likely at this point) - who will they be serving ads to?
But while the ad revenue is probably fine, the API revenue is definitely what they think the cash cow will be, and practically speaking they could lose 75% of their users and still probably not lose a whole lot of value just due to the sheer amount of historical data they have (especially if they start selling deleted content.)
