The headline has important context: “YouTube bans Steve Bannon's podcast channel hours after Rudy Giuliani appeared on an episode and blamed the Capitol siege on Democrats” At some point the lies need to stop.
If you say "Democrats have ignored certain classes of Americans and pushed them to the brink and this is the result" - it's a heavily editorial opinion
The press overall uses these types of editorial lies daily.
The Guardian today is Blaming the existence of COVID on Boris Johnson, unsurprisingly. To me it's a stretch, and basically a lie, but well within editorial distortions we can expect these days.
I'm not fan of either of those Giuliani/Bannon fools, but this kind of 'lie' I don't think is ban-worthy.
Youtube might be using current political conditions I think to go after those they don't like.
If Giuliani was on the podcast actively calling for further acts of sedition - like he was at the rally a few days ago - then it would be a ban for sure. But he's not, so it's not.
