In Mr. Zatko's previous appearance before Congress* in 1998, he was addressed by his hacker nom-de-plume, Mudge. Perhaps they see fit to continue this practice.
The use of the Mudge is certainly the weakest of the indicators I've presented; what do you think of the strongest of them, the unusual use of emphasis? What do you think of the three of them taken together? If you were the author of this document and you just found out that the public would never see it, only officials at the SEC et al - would you feel like this document was likely to be effective for that audience? Is there truly nothing about it you'd change in that circumstance?
I do think there is a good reason for bodies which are meant to dispassionately find facts and enforce regulations to prefer plain language and straightforward argumentation. But even if that weren't the case, it really wouldn't reflect on my argument. Additionally, everything the document alleges could be true, and the allegations worthy of discussion - I haven't argued that they aren't true or that we shouldn't be discussing them, I have no way of knowing if they are true and am ambivalent about whether we should give them oxygen - and that would not reflect on my argument.
I go into slightly more detail on this point here: https://news.ycombinator.com/item?id=32603317
No, I don't believe it would read the same without emphasis. Especially since the emphasis is often on superlatives rather than the substance of certain statements. I'm not sure what to say other than, "emphasis is a tool of graphic design that does, in fact, function." It guides the eye and enables the reader to skim, and if you took away the emphasis, this document would be less effective, at least if the goals of the document are what I have argued.
Your questions seem reasonable except the fact they're about him!
Do you understand his (very populist) history?!
It's pretty apparent that one of the intentions of this document is to get Musk out of hot water - totally separate from "protecting the internet" and not a particularly populist goal.
I'd speculate this represents a collaboration between Musk and Mudge's legal teams, probably in exchange for Musk funding litigation from Mudge regarding wrongful termination. That's all speculation, it's just what makes the most sense to me.
I'd write like there's no way this doesn't leak to the public eventually. It's Twitter we're talking about. Juicy gossip is the point of the platform so of course it's going to get spread. I don't know that it undercuts its message though.
