All the non-jocular speculation I've read here regarding the (apparently glass) acquisition probe has revolved around it being bulletproof glass.
Perhaps it is - that by itself does not demonstrate a Critical Person exemption. One can posit, inter alia, such was requested not for Mr Musk but for an ex-wife, for one or more offspring, and so forth. THAT would raise eyebrows and most certainly would be front & center for the Board's Ethics committee, with the discussion revolving around whether diminishing the prospect for pain and anguish for a Critical Person be the responsibility of the corporation.
Perhaps it is - but for Mr Musk himself. It boggles the mind that his venues - houses, automobiles etc. - already would not be so equipped. But if there is a new Latest & Greatest? Is Tesla Inc. responsible for such?
But perhaps it is not bulletproof glass at all. After all, there are any number of sources for such a product....they ALL are "out of supply" so to speak? Perhaps it is for electrochromic glass. Or a special soundproofing material. Those two possibilities, however, also instantly would go to the Board's Ethics Committee because alternatives - very, very mundane alternatives - exist and it would be supremely difficult to argue successfully that the functioning of a Critical Person could not be obtained by any of those other possibilities.
I post those not to pass judgment as I have no more inside information as to the whole story than do others. Rather, it is to dampen the judgment that, since Tesla needs Mr Musk, it behooves it to supply bulletproof glass.
