I really don't understand why security concerned people use Google's product in spite of knowing that Google steals everything and compromises user's privacy.
As far as security goes, I trust Google way more than any other site to handle my credentials properly, follow security best practices, use the highest level of encryption where applicable, keep servers up to date and patched faster than anyone else, etc. Outside of Google+, I can't remember the last time there was a major security incident at Google, when they happened, the impact was minimal (contrast this to say the Apple Cloud leak which led to the infamous "fappening", the Marriot leak, the Equifax hack, Target, etc). Breaches and 0-days happen, but as far as I know, Google is going to be the best it gets when it comes to security.
Now when it comes to my privacy, no. I don't trust Google as far as I could throw them.
