Google, facebook etc. They don't pay tax. Do you? What do you get for your tax? What do they get from tax revenue to which they don't contribute their share?
The kicker is going to be when you think "What if I didn't want to use any google product. And I was willing to pay real money to achieve that. Could I?" Then you realise google still have all your mail and browsing history. Paying. Yep. How? Through the nose.
If you think you're getting Google products and services for free, you're just not paying attention.
It still seems to be a pretty good deal when you compare the bill for GMail, YouTube, Google Search, Drive, Docs/Sheets and Maps to the cost of the phone bill, cable tv, and internet.
