I want to point out there's a big difference between judging people without nuance and what the parent post says. To me it seems you read a lot in between the lines on the post above which I didn't get nearly the same reading on. I took it simply as "I see Facebook on a resume, it's not a full positive for me like many may see it in the tech world" and would be a possible ethical red flag.

I feel the same at a personal level and Facebook is far from the only company on my mental list there, but with any of these it is not a categorical judgement or an immediate eliminator of someone in any situation.
