I agree that this is a wider problem with streams as a genre.
I think the main problem is that starting a stream and talking about whatever in order to appeal to a larger and larger audience is rewarded rather than good research and preparing high quality content, like on YT or TikTok.
It’s just not possible when you’re streaming and would defeat the purpose. It’s all quantity over quality, so assholes get to the top.
In communist Poland some things you could only hear and record live, because that was harder for censors to stop. Even then there were censors backstage crossing out forbidden lyrics from the sets. However they would often get ignored as an act of defiance, especially at punk rock concerts.
But there was no way to officialy distribute these kinds of materials and doing so could land you in jail.
So unless you had some kind of underground source, your best bet would be to go to a concert and record it.
