I actually always thought there was a possibility that what happened to AOL might happen to Google / Facebook / etc. I.e. people inherently don’t like extreme walled gardens, and will splinter off into more open, more random, more innovative spaces. I think the pendulum had swung back over to an early AOL like very limited set of 5 or so big “platforms”, and the issues with that were seen again, just like in the late 90s when people were ditching AOL for “the real Internet” en masse.
I don’t know how important this is to users of Vivaldi, and I don’t know how good Vivaldi can make their blocker by middle of next year, but this may force me to Firefox. Or maybe someone makes a local proxy like in the old days to do ad blocking Idk.
