I think the problem is the bubles we are in. If everyone you ask is boycotting Reddit, thats cool. But those people all being on Lemmy is a huge filter and your not getting an accurate representation of all Reddit users. As you say, most people stay there. Us more involved or tech savy people are the ones leaving and talking about it hut we certainly are the absolute minority (unfortunately).
Not dying, but decommercializing. Glad to see it, unless people will just go to something worse.
But I think people are overexaggerating how fast and how big this process is. Most people are still on Twitter and Reddit, it's just some people (maybe 5%) that left. Especially on Twitter, where it didn't really get worse since it got bought.
