Honestly I don’t think we will see much of a swing. The people who are fed up with it will move to platforms like this while the vast majority will remain on sites like Reddit or twitter. It’s the same with adblockers, most people don’t bother with them because they just don’t care. That said, I don’t see anything wrong with decentralized sites like lemmy staying on the smaller side, it draws less attention from the same people who have ruined the larger sites.
I've seen it said before but I'm shocked that most people apparently don't use an adblocker. To me, the internet is unusable without it. Try to open any wiki hosted on fandom.com for example.
