It’s not the same. Most people calling the 2016 election a sham will admit that Trump did technically win by the rules as written, but also think that those rules are bullshit because they allowed a multi-million person majority to be shut out in favor of a malevolent moron. The people saying Biden lost are saying he literally cheated and that there’s a conspiracy of thousands of government employees collaborating to break the rules and subvert the will of the people; that the multi-million majority literally doesn’t exist. This is just as disingenuous as comparing the top secret documents that Trump hid to the ones that Biden and Pence handed over immediately on request.

being justified or not has nothing to do with whether something is violent. if someone is getting hurt, maimed, or killed, that’s violence, no matter how much they deserve it.

Meta/Facebook and Google/Alphabet are very different from Twitter/X. The first two created parent companies under which their large brand names still exist, but are now managed along with their other properties (Instagram, Snapchat, Waymo, Deepmind, etc.) Musk, meanwhile, is trying to completely burn down the Twitter brand for some incomprehensible reason.
