Does it really matter?
I get google mail, with 6+ gigs of quota.
I can make free calls via google's email website.
I have a google phone number from GVoice. If my phone service is deactivated, I still get calls and texts and transcription. All I need then is to log in via a free wifi.
I have all my contacts saved from my phone, along with free recording and voicemail transcription.
I have a full history of what I've previously searched, along with what links I found.
I have a chat service hooked up to my email.
And now, I can back up critical files like my resume and documents on GDrive.
I also make 7.25/hr , with no benefits, nor any employee perks whatsoever. I am also a "part time employee" and in an at-will state. I had to take this job after unfortunate events. I like eating.
What google provides is something I COULD NOT pay for elsewise. If I pay with some datamining, so be it. I gladly accept that trade.
They'll only datamine a poor person. If my data (and lack of money) is good enough for Google, good on them. I would value what I'm getting at $50/month.
