In my opinion, what Google is doing, though not on the best interest of it's users, but may have nothing to do with bitcoin privacy. I think that the activities on Google site may have no direct effect as far as Bitcoin anonymity is concerned.
In addition, i am yet to see the impacts that Google has made to shield or protect it's users privacy, but the mixer space is doing excellently well by giving crypto users the needed anonymity required to carry out transactions everyday.
I have not heard complaints of data breach or information leakage from mixer users, unfortunately there are ugly news that has indicted Google on it's privacy policy.
Honestly, mixers are doing great job as far as security, reliability, and trust are concerned, and i am sure that Coinomize biz has maintained a very high standard that everyone can see and testify.
