That isn't true. I use almost none of the large tech; no Microsoft, Facebook, Apple, Google, or AirBnB. I pay the massive $12 a year for email that doesn't scrape data because my privacy is worth it. It isn't difficult, you just have to value your privacy and quality of life.
People prefer convenience, just like they choose fast food and processed food rather than cooking real food.

No, there aren't. So called "socialist" or "communist" governments of countries are 100% capitalist. Capitalism is defined by the relations of production, not what a government or political party calls itself.

I use them even less than that. But I'm not sure what your point is. My individual choice to use the services of big tech companies as little as possible has little to no bearing on whether they force themselves onto society, and give many people little choice in whether or not to use them.

I mean, I also try to get a new phone as rarely as possible, but my ISP requires me to use one—and not just any, but a new model (within the last 2 years) of "smart" phone that their own proprietary app supports—just to change the security settings on my router. And that is the most minimal example of how corporations constrain society to choices that benefit them and not us.
