Earlier quoted context omitted.
I didn't mean to say that I have had absolutely no interaction with any existing Apple or Google service or technology. I'm neither a fundamentalist nor a hermit. Rather, whenever it is my choice, I prefer to select products and technologies that don't belong to Apple, Google or similar companies.
Sorry, I did a poor job of making my point. @hkarthik implied that it's impossible to use technology and also boycott Apple and/or Google. I agree with them. You seemed to disagree by saying that you do boycott Apple and Google. The point I was trying to make is that you're part of their revenue stream even if you yourself don't have any consumer relationship with them. That's why they feel like a monopoly to so many…
One thing I try to do is to minimize how much revenue they get out of me. For example, I use uBlock Origin and uMatrix to block their ads and scripts, their cookies, Google Analytics, etcetera. I hope they are losing money on me, that'd make my day!
