Okay, so first let it be noted that you linked a list of 15 bad examples and when I called them out you called me cherrypicking, then when I stopped cherrypicking your immediate response was "I don't have enough time to engage with all the examples". Jeez louise, you literally just asked for me to "open up tangents". I was satisfied summarizing your list as ridiculous garbage that made no sense. The reason we're still talking about it is because you wanted to. Okay, let's only talk about Kathy Griffith for some reason.
The reason YouTube did not ban Kathy Griffith under rules for threatening violence is because: 1) The purported threatened violence was not threatened on YouTube, it was for a magazine. 2) The purported threatened violence was not a threat of violence, it was a depiction of violence. Those are not the same thing, but I'm totally fine with banning for the latter. You're the one that isn't fine with the thing you're arguing for. 3) The threat occurred at a time before YouTube put these rules in place. Updating your rules isn't being a hypocrite because you didn't time travel after doing so. It's also literally what the left has been asking for for years.
But separate from that, your position was that the left didn't deplatform her, and unsurprisingly, it did. CNN, Home Of The Left Biased Anti Trump Fake News, fired her immediately. So great, it is agreed that celebrities face significant reputational consequence for doing things that aren't threatening violence but are adjacent and might be perceived as uncouth.
Again, I need to stress that the person in the OP directly threatened violence. She didn't say "I hope the people who own YouTube get shot". She didn't say "If I was alone in a room with YouTube lady, I'd punch her in the face". She didn't do a music video of robot YouTube getting exploded. She did a direct and personal threat to murder a specific named individual. And you thought the really important aspect of this story was talking about Kathy Griffith.
Let's recap the thread: You think that no one should be banned for threatening violence on YouTube. To support this argument, you link a bunch of people, some of whom were deplatformed, most of whom aren't threatening violence, and most of whom weren't doing the thing they're accused of on YouTube. You then insist I'm being uncharitable to the evidence by not taking more seriously the threats of violence, which again are mostly not threats, and again, you don't think we should take actual threats of violence seriously.
You should advance the argument you actually believe in, not do a bizarre strawman devil's advocate where you say "I don't believe in banning people, but imagine if I did because I was a tyrannical anti-speech leftist, then I would be a hypocrite, because I wouldn't ban this anti-Trump celebrity, which makes me a hypocrite, checkmate".
