As others have mentioned, this is a matter of threat model. To be realistic, a sufficiently determined government will always be able to access your communications, but companies like Facebook and Google can only access them if you give it to them willingly. On the other hand, if other people you communicate with do this by themselves, then you’ve gone through all that effort for nothing. It’s also worth pointing out that it cannot be proven that a regular phone does not have corporate spyware installed, so this may be another way your information could leak to companies.
That said, it is pretty insulting that tech companies have decided that they’re simply entitled to everyone’s private communication data. That for me is probably the biggest motivator in trying to avoid their services as much as possible.






The funny thing is, before Google existed, people had no idea if their marketing attempts were working. Maybe they had some ways of knowing or guessing, but there was no way to know how accurate their metrics were. Internet-based advertising, and tracking-based advertising in particular was supposed to change that.
And now that we sit here with a duopoly of advertising giants, we’re back to the stage where marketers just have to trust that their provider is giving them good helpful information. And how are they supposed to know whether they really can believe it or not? They can’t of course! So we’ve come right back to where we’ve started.
But considering they still spent tons of money before Google and Facebook gave them these “analytics”, it looks like they probably don’t even care that much.
