My subjective opinion is that yeah it is unethical, but not more then so many other things we normalised.

Systematicly slaughtering animals for meat for example.

I am not a vegitarian by any means. You cannot fight on all fronts at once and have to pick your own battles in context of your own lifes challenges.

Cars poison the air and kill many people, i dont drive a car for that reason because thats a fight i can fight. I have sensativities with food, so i am not cutting out meat. (I aim to do so some day)

I moved to linux some years ago by getting help from an llm which requires datacenters build by malicious companies. I don't have a google or meta account and my cloud and media is hosted locally on recycled hardware. Where for others those services require datacenters build by malicious companies.

Life is various shades of grey.
