My anecdotal impression is that YouTube and Twitter played a big role in spreading election misinformation. The main basis of the Kraken conspiracy theory came from a YouTube video which was spread on Twitter and I remember numerous election integrity fake news tweets getting hundreds of thousands of retweets from a large right-wing echo chamber. It may have been worse on FB but I do think the asymmetry of attention and scrutiny is far out of whack.
I'm going to guess the reason is that congresspeople and journalists see Twitter as their domain of control now and benefit from the privileges of a blue check mark and the other side being kicked off. Probably Zuckerberg's lack of charisma and physical appearance isn't helping either, however unfair that may be. Another reason might be that the FB newsfeed lacks transparency unlike Twitter which contributes to distrust.
