The whole "one individual talking to another" aspect of the internet of the 00s is gone. It feels more and more like an "everyone is talking to you and hearing you, like it or not". Facebook is only an example of that - and even if it didn't enshittify, I find unlikely that it would've kept that aspect.
I also wonder if my experiences with Orkut wouldn't be similar to the ones of the author with FB, if only Google didn't kill Orkut. (It was a big thing here.)
