I am aware of that, good to point out though. However I was wondering because the wording "you can still maintain the discrimination" implies awareness and perhaps conspiracy. For example if I was talking about "implicit bias" I might have said something like - "it doesn't modify existing implicit biases and institutional constraints, which have been responsible for ...". But even then it would be good to see what exactly those biases and constraints are at Google.
On the topic of "implicit bias", it's also useful to add that it doesn't have to be just a personal "implicit" bias, it could institutional as well, incentives and rules that combine to exclude certain groups more than others, in this case women. Though then it's not clear how they would fix it, given that it's implicit. Maybe hire an outside consultancy which will be able to identify it better (since they are not part of the culture and not affected by same incentives)...
