He didn't say anything at all about OP's ability to read the article. "bold assertions" clearly refers to the 3 points he lists and you seem to be deliberately misreading.
OP made some very bold claims about how Google works internally and unless he's a first-hand witness (Google employee), he really needs to provide some data of his own to back his assertions up.
I read the OPs comment as partly a comment on how Google has been releasing social commentary without releasing the raw studies specifically on gender and salary. They were being investigated for cheating women on salary.
I read the response from the Googler as an appeal to authority. If Google doesn’t release the study, they open themselves up for conjecture and skepticism.
To criticize OP for being inaccurate is fine, but absent any references, Google is making the same argument as the Googler.
