It's not "Engineer thinks PM is a bozo", it's a post explaining a very concrete, objectively negative behaviour from the PM team. I've worked at companies where that sort of behaviour was rampant, I've worked at places where it wasn't, and the difference in the end product is palpable.

Second, even if it's just anecdotal, I have personally been experiencing issues with my tMBP at work that I haven't had with any previous laptops going back to a G4 iBook. Stuff like random crashes, parts of the screen failing to render properly, etc. IT says that they're experiencing more of that sort of complaint with the current gen than they have with others in the past. The "sensationalist anecdote-driven news cycle" is blowing things out of proportion, to be sure, but there does seem to be some measurable degradation in their Apple's standards as of lately.
