The question should be whether TSLA shareholders think he is, and I think most of them probably do.
(I don't own any TSLA, btw. But from what I've seen, many of his fanboys love him for being conniving while simultaneously claiming he's done nothing wrong. I believe this is an example of double-think. But the subject of this discussion is how these people might react to Elon Musk controlling Twitter, not whether their allegiance to Elon Musk is rational and rhetorically consistent.)
