I'm as comfortable using Google apps today as I was a week ago, because I figured out long ago how to disable Keystone permanently. (It wasn't easy.)
But I am rather pissed at Apple because SIP is a global switch and with it enabled, there are several significant, legitimate things you cannot do with your own computer. SIP should work like sudo, not like a meta version of root. If it did so, nobody would have been affected by this week's Google nonsense.
