PG did a good job (as tptacek did) of trying to spin this [1] but the bottom line is there aren't comments because somehow it's not good for YC. (Which is fine of course since it's YC's sandbox.)
Fully see the problem of course with the "outing companies that were still under the radar". I would have just left it at that. The rest is just a distraction that gives people a reason to refute the additional points made.
In selling it's best to just concentrate on the strongest angles. Otherwise you give people an opening on something that doesn't even matter or a problem that can be solved.
[1] Reminds me of when trying to "explain" to children why they can or have to do something. The bottom line is "we're your parents and that's why and a different set of rules applies to us".
Why do they feel that is bad? And have they ever been on on HN job postings (if so how long ago)?
