Speculation not from a social scientist as their job but a worker within Google apart from being grossly misplaced begins to sound eerily similar to the ravings of self obsessed supremacists cherry picking science. This is what hostility looks like.
And women then should be rightfully wary of all these fragile men who will watch them like hawks looking for any excuse to confirm their bias.
Google should send a memo explicitly stating anyone who thinks women or any group lower the bar should leave. This is not a place for bigots. It's a place for mature educated well adjusted adults to work together.
Anyone who supported that letter should in good conscience leave the organization which is 'lowering the bar', a definition no random individual not suffering from extreme hubris is 'qualified' to set and the prerogative of the organization and experts qualified for it.
If you are obsessed with diversity lowering the bar you can become a 'measuring the bar expert' and invest the time required educating yourself to become an expert before presuming to speak with authority you do not possess about a scientific field that does not trade in certainties.
