@chrisisgr8 Sorry I'm not seeing it. Google Search and Youtube still work for me (for the limited kinds of videos I watch).
Birdsite was the worst of the big social networks well before 2022.
I have lots of complaints about Discord, but none of them are new or really exacerbated in 2023.
Windows...okay, I don't know this one, since I ditched Windows in 2017.
The only one where I agree with your timeline is Reddit. I'm hoping #InfinityForReddit gets converted into #InfinityForLemmy.
