From my perspective absolutely nothing has changed other than some new subreddits hitting the front page. The topics are the same. Maybe a little more international content——I can’t recall “ich_iel” ever making it to the top before.
I understand most users are lurkers like me. With that in mind, I don’t believe these blackouts will accomplish much. They’ll probably accelerate the homogenization of the platform and the race to the bottom in terms of quality, but that is happening anyway. I already know Reddit is mind-numbing days-old TikTok memes, I use it anyway because I like the interface more.
Edit: it isn’t that I am against the blackout, I just think in realpolitik terms it is not effective since most people are really not that invested or interested in participating in activism for their memes.
