Source is the link that I posted. They study this specific topic, and you’ll be hard pressed to find a better data set out methodology I think.

The only major tech platform that leans red is Twitter after musk bought it, unsurprisingly.
Mind you, I’m not taking sides here. I gave up on both teams at least a decade ago. I just don’t think this is behavior we should allow from tech companies either direction.
My not is that having a slant is perfectly acceptable, having tech companies so large that their comment policies affect the Overton Window isn’t.
I don’t have to care if the Washington Post or Financial Times have a political leaning, there are alternatives. Less so with Instagram. You can pry Facebook out of my mothers dead hands when that day comes.
