The pilot has an excellent personal and professional reputation, but was involved in politics that may have placed him in conflict with his employer.
And there are pilots are in direct conflict with their employers through involvement in their unions, which can at times be quite acrimonious. I've never heard of a case where those conflicts have led to a deliberate accident. So your point is?
Absent evidence to the contrary, this kind of implicit allegation is close to libel.
There are plenty of pilots with passionate political views. I have yet to learn of an accident deliberately caused to make a political point. If this one is the exception, I'm open to that possibility provided that there is actual evidence to back it up. The US FBI has analyzed Captain Zaharie's computers and has not found anything suspicious. Time to stop beating this dead horse unless something incriminating turns up, particularly in view of the fact that the man is not around to defend himself.
