Nothing of value to be found outside the few people that actually give a fuck making YouTube videos

Maybe where you live. Massively popular platforms like these are pretty good at gathering people for rallies/protests and spreading investigations, news and fundraisers.

Best case scenario is people switch to decentralized media, worst case - the momentum for their rallies is ruined and ppl get arrested for saying the wrong things online. Then (most likely) these platforms get unblocked and everyone forgets about it.
