"no revenue impact so far" how is it possible to be this short sighted? Of course people using the official app and website without adblock won't have gone anywhere. It wasn't every subreddit, they're probably just wondering why so many aren't working. But if this continues, and tbh the damage is already done for a lot of people, users and moderators who generate the content and make the site usable for the zombies will leave and it will just become twitter 2.0, an increasingly bad shitshow, some subreddits will be left with no quality submissions at all.
Also: "still in conversation" with other third party apps? The entire point was to make the price so high they'd have to shut down. Plausible deniability I guess, and those other third party apps with way less users will probably just be able to sell subscriptions (can't even use ads, though)
