Now that social media sites are banning Trump, I can see them moving to ban communist/socialist/anarchist accounts under the same pretext of "fighting extremism" or something.

The tell is the phrase “ideologically inspired”

Yep, that just screams purposefully vague. It's possible that they'll also try to do some kind of crackdown on the right, though, it wouldn't surprise me if they're scared shitless of the chuds rn. These are privileged, sheltered, civility-obsessed people who've just seen that there's a large number of really pissed off folks in their country who want their blood and are willing to kick in their doors. We all know that fascism is compatible with the interests of capital, but the mob is after the Dem leadership personally. If they'd have any lick of sense, they'd go nazi hunting now, but it's the Dems we're talking about. They could absolutely fuck it up simply out of fear of not appearing neutral enough.

Which means they absolutely will go after the left more than the right. For every group of facebook Q boomer they'll bust for openly discussing how to get an anti-tank missile for :dem: , they'll go after ten BLM organizers. Biden will be in full siege mode from day 1, it absolutely will be a priority to neuter and co-opt any opposition from the left. Horseshoe theory and framing everybody who's left of Kamala as a nazi, and framing all nazis as a nacho socialists, will be the ideological foundation for this.
