The point of web diversity is to allow people to use what browser they want. If you like Firefox use it, if someone else wants to use Brave, let them.
Brave is not a bad browser, turn on what you want, turn off what you don’t. The idea that there must be a right and wrong is stupid.
To write off an entire browser because of one person at the company doesn’t really make sense.
To write it off because “it’s chromium” is also a problem because they don’t support chrome decisions and are not applying their trash to it.
To write it off because crypto is attached is ignorant because you’re welcome to just turn those features off.
You’re part of the problem. If someone using Windows bugs you so much, go read a different post.
