Exactly. Main problem is that people treat a phone or computer as a tool that serves their needs and might not realize that in fact it serves someone's else needs. They cannot see the traffic their device sends to Google, they cannot examine Google's comprehensive databases. Data collection remains unnoticed, there are no icons and no warnings. Opting out of data collection is inconvenient. When I need to log into Google or any other large company service, I have to do it in a private tab. When I want to run skype or slack, I have to create a separate OS account for them because major linux distributions don't have any protections preventing slack from reading my browser's history. Oh, and did you notice that Linux Slack app opens a browser to log in? I guess the reason for it might be that they want to store cookies in the browser and track the user across the Internet.
