One can assume they already are. By virtue of having a disproportionate representation of one political party within their ranks (which they do), you can argue that a lot of their decision making (however benign/simple/small) will fall in line with that parties platform, or end up promoting that party in some way. Right now from my point of view, it absolutely looks like the big social-media companies like Youtube/Twitter/Reddit/etc are actively purging large conservative opinions/voices in anticipation for the US election coming up. It's downright Orwellian that we allow them to have such a huge impact on political elections under the guise of "community standards". Those same community-standards that are touted for protecting the vulnerable are acting as camouflage for political meddling. As for Tik-tok, I'd ban it just for the degenerate social impact it's having on a large section of our youth population. Ditto for gang-glorifying, misogynistic rap music.
