Yeah, that‘s a comparison that does make sense to make. I’m sarcastic here.
Are people deliberately missing the point or intentionally evil?
At some point, many free speech maximalists get driven into an ethical corner. This is one of them, and we discover that all of a sudden, many of them only support propaganda that they like. (But they will bend over backwards trying to come up with weak reasons for why bullshit from RT is totally different from bullshit from Qanon.)
Even more simply, companies like Facebook and Twitter are stuck in the middle if for no other reason than they can't lose either half of their audience.
They're happy if a few extremists peel off to their "free speech" platforms, because it's less headache for them and they don't have to worry about those platforms appealing to the mainstream. They themselves will obviously never do anything to lose the mainstream on either side.
All I recall was accusations by political parties from both sides.
Just because some content got popular amongst some cohort, it doesn't mean it was being pushed as an agenda. That is a problem any platform that depends on user activity to surface content will have, that you might see whatever the other side wants to share too.
