Earlier quoted context omitted.
"Flexport is hiring" posts were popping up like weeds here on HN for a while. And they never allow comments, which I found to be highly suspicious.
"We're hiring" ads from YC companies get special placement on the front page, and (AFAIK) they always have comments turned off. Nothing nefarious about that.
If these companies are truly as great a place to work as they claim to be, then they should be able to very easily defend that in a comment thread. The silence from a lack of discussion on these hiring posts is deafeaning.
