I don’t disagree with that. It’s just that most browsers are built that way, unfortunately. Nothing is free, not even Firefox. If you want to sell it, it’s hard to maintain reasonable expectations that people won’t just build it from source instead of buying it. Something 100% free can’t maintain itself over long time.
Only English ones?
