Key difference: You elect your government, and if you aren't happy with how they're doing things, you can vote them out. I never voted for Zuckerberg, Bezos, Cook or whoever runs Google.
If you aren't happy with Amazon, Facebook, Google, Apple, etc, you can choose not to be a customer of them. You can't opt out of paying taxes.
Facebook shadow profiles would suggest otherwise
I'm not a customer of Google nor Facebook, but they're still tracking me all over the internet.
I'm assuming you're intelligent on account of being able to write a comment and doing so on HN. Have you really never heard of FB's shadow profiles and the like? Are you being wilfully ignorant?
