On the subject of Brave:
https://www.reddit.com/r/browsers/comments/1j1pq7b/list_of_brave_browser_controversies/ it really has a little bit to many controversies. (And the list is downplaying some of it, the wikipedia clone added wasn't just some random one, it is was the one created by the alt right, neo-nazi Vox Day. Addition of which by the CEO should be enough to not want to use the browser at all).
Some of the horrors are also going to be load bearing for some fixes people dont properly realize because the space of computers which can run windows is so vast.
Think something like that happend with twitter, when Musk did his impression of a bull in a china store at the stack, they cut out some code which millions of Indians, who used old phones, needed to access the twitter app.
