Absolutely not surprising. Just ask HN users what browser are they using and the answer will be Chrome or Chrome clone in 99% of cases. I even got a reply once along the lines "why do you use Firefox?". I was at a loss for words.

I also observe exact same pattern in two different countries among experienced IT workers. They mostly don't care at all about any non-tech implications of the services or employees they are using. Creepto, gambling, tax evasion, supporting monopolies, etc. - all fair game.

PS: I'm guilty of the same too, in other areas. But at least I'm selfaware about my transgressions.
