I don't think that there is anything inherently "conservative" about misinformation about a disease in the midst of a pandemic. If Biden decides tomorrow to claim COVID is a hoax, vaccines have microchips, drinking bleach cures COVID, or attempts a violent coup against the government, it'd be fair game to ban him from the platform, regardless of whether he's considered "liberal" or "conservative."
I did go through the "Ctrl-F" for the link, and it was a list of terrorists, Holocaust deniers, neo nazis, and hate speech. I don't think being a conservative necessarily entails any of these things either, even if they are often linked to being "*-right."
