I bet the "Reddit won" statement is a bit premature. Yes in a sense it pushed forward what they wanted to do kicking out third-party apps and moderators who didn't toe the line. In the end, they kept the traffic but it must be mostly the silent majority of lurkers. I bet a significant chunk of the minority providing content and discussion went away or at least is trying out alternatives and finding a new home in the likes of Lemmy.

Time will tell if Reddit stagnates/declines content-wise.
