I grew up during the internet adoption phase in the early 90’s. It feels like that. At the time mainstream media/news papers completely dominated the flow of information. The internet temporarily changed that for about 20-30

Years but then these centralized platforms popped up Twitter ,meta etc and became dominant. It seem to me to be a cycle with tech:

Self sacrificing people build open systems which are subsequently captured by power and greed driven sociopaths which are then destroyed by self sacrificing people building free and open protocols………

There always remains a remnant to bring back the good.
