I'm generally considered knowledgeable and I'm just thinking from the perspective of owning a company and employees taking these actions instead of coming to talk to me, showing evidence of my poor management decisions.
This whole text reeks of a employee vs employer situation, which is never good (you're in it together), so probably it is good that the person left the company, for both parties.
Perhaps I'm naive, or not American enough, US work culture seems harsh to me sometimes, especially wrt work ethic and hierarchy.
I'm off now to find what PMC is, thank you.
Edit: Looked around for sometime, no idea still what PMC is.
I guess lyu07282 is what I have taken to calling a "Judger". Always labeling, always judging, always seeking the moral high-ground, never realizing the lack of nuance that must exist in short texts. Never thinking "what if this was meant in a kind way." Oh, and I see the irony, it is intentional (feels bad right?).
I think it's what tearing the US apart at this very moment. Always Us against Them. Most people are kind you know. I really thought I did my best to add nuance.
