I think this is what’s happening.
If Google loses appeals, Mozilla (and many other browsers that rely heavily on getting their revenue from Google), will have to find new ways to generate revenue. Unfortunately, they seem to be looking for the easiest way out, and that’s selling out their users.
To me, the ethical thing to do would be to allow people to make their own choices about their own bodies and their own lives, unless the don’t possess the mental ability to do so. Anything else would be unethical.
