Do you see EAs taking Émile seriously? Émile is banned from the forum, and I would guess most people who know the name at all know it as the name of someone who has been persistently unreasonable in their criticisms.
(btw though, your comment says "he didn't be taken seriously", but Émile is a they, not a he)
Dustin Moskovitz claims "Tesla has committed consumer fraud on a massive scale", and "people are going to jail at the end"

Not super EA relevant, but I guess relevant inasmuch as Moskovitz funds us and Musk has in the past too. I think if this were just some random commentator I wouldn't take it seriously at all, but a bit more inclined to believe Dustin will take some concrete action. Not sure I've read everything he's said about it, I'm not used to how Threads works
Forum post saying the same thing, with some discussion: https://forum.effectivealtruism.org/posts/SM3YzTsXmQ6BaFcsL/you-probably-want-to-donate-any-manifold-currency-this-week
I feel a bit worried that everyone would like to believe that EAs will receive criticism in good faith, so they will be excited to tell you this is true, even if they can't really be that confident. I hope they're right, but worry they're really saying "I, personally, would receive this in good faith, and I think others ought to, and I don't see why they wouldn't" or something like that.
I would guess from things like the Bostrom email controversy that you'll get at least a couple of frustrating comments, and perhaps a small handful people who will be reflexively and unfairly judgemental. I would hope and guess that these experiences will be outweighed by people being grateful for you raising your concerns, including from people who ultimately disagree with the concerns. But obviously it's hard to be sure (even harder given that I don't know what the concerns are).
I'm a bit worried this comment raises the barrier to commentary, so let me try to lower it by saying you can feel free to DM me if you think talking to me privately about your post will help you get it published :)
