Furthermore, you don't get to choose what your "UX issues" are. "UX" quite literally stands for "users experience", which is on the other side of the spectrum from "developer experience". As a dev myself, I know it's difficult not to conflate the two, but acting like issues straight up don't exist is blatantly hostile.
I have no personal qualms against Brave. I'm just another developer who wants a browser, and Brave's naive featureset doesn't appeal to me: that's fine. I'm just helping other, similar users make the right choice.
