You're probably going to want to take a look at how your smartphone battery is made. You're taking a principled stand on the basis of not using a browser from a company cofounded by a guy that voted differently than you, but it sounds like you're willfully ignoring the child slave labor used to create the device you're using to type that opinion.

Do as you please, but it makes no sense to me, and doesn't strike me a principled at all: it's basically virtue signaling. But then again, I don't view people that hold different political views as my enemy. They're just people I disagree with, and they can still make a great browser, even though we disagree on some things.
