Oh, totally. It's possible it's a coincidence, it's just also possible that it was Boeing. I'm withholding my final judgment because I can't know either way with any surety, but I'd be incredibly unsurprised if, were we to ever determine a definite cause plus the existence of a perpetrator, that it was Boeing. Either way, fuck Boeing.
If I was one of the remaining five recent whistleblowers, I'd be looking over my shoulder hard right now.
