We have the benefit of hindsight on this particular incident, which I think strengthens my point: it seems very likely that Elon was being purposefully misleading about the circumstances surrounding this incident, that they did not actually endanger his child, and that the ElonJet account had nothing to do with Elon's encounter with this person. I think it is reasonable to say your comment was on topic. However, I strongly disagree with your characterization that you "brought the conversation back on topic". Considering that there was already evidence on the day this was posted that Elon was acting with intentions other than genuine concern for the safety of his child, I think a "is Elon trying to get rid of an account he doesn't like?" comment thread is very reasonable and eminently on-topic. When Google cancels their social media product because "they are refocusing priorities" a thread about "hey I heard they had major security issues with the product, so they probably canned it rather than dealing with the fallout of a data breach" is totally fine, even if the official blog post mentions nothing of the sort.
Actually, if you came into the comment thread where a dozen people were already discussing this possibility, and just left a reply to one of the comments of something along the lines of "oh I guess Google thinks social is too hard, they want to focus on Android now"…that's kind of weird, right? This thread was operating under the assumption that Elon was basically lying, and trying to intimidate the ElonJet guy. The person who was going to fund him was clearly doing it because he thought he was giving money to the little guy standing up to the SLAPP abuser. When I said you waltzed in it's that you just came with "I believe every single word from Elon's side of the story and this happens to mean that you are funding a terrible thing". That was not the assumption that this thread was operating under. You can disagree with that assumption but you didn't go "guys why do you even think this is a SLAPP lawsuit?", you went "why are you funding a doxxer who might murder children". How is this an improvement to the discussion?
