Nuanced opinions
1) The fact that he cheated on his wife isn't particularly relevant, other than the lack of a prenup meaning she owns half his stock (4% of the company).
2) The fact that he slept with a subordinate shows bad judgment, but isn't a huge deal (although improper and opens up potential quid-pro-quo lawsuits)
3) The fact that he slept with a Chinese spy is a huge deal.
4) The fact that there are allegations that he was aware that they were selling illegally to China is a huge deal.
5) Even though those export control were arguably bad, the law must be respected and the being seen ignoring the law would have a chilling effect on appearance of a fair democracy.
6) There is definitely a demonstration of lack of judgment (getting caught selling to china rather than maintaining plausible deniability), (sleeping with a spy rather than just hiring an escort)
7) Despite all of this, in theory he would arguably still be the most profitable CEO (if he doesn't get charged with a crime, AND if there are no other issues to discover) in the medium term, but where there's smoke there may be fire. Does this raise the odds of circular financing and other shenanigans?
Agreed 3 & 4 are (justifiably) the source of the hullabaloo. I assume on #7 you mean blatant round-tripping... Because they are definitely engaged in circular financing, out in the open.
