I've been using Firefox on my android phones for years though, I don't remember it ever being more involved then setting it as default on the popup on first launch.
That doesn't surprise me, and yes it was always because of anti-competitive practices, so I'm all for more neutrality, I'll just add 2 shower thoughts:
Seeing that Brave is at the top of the browser list, I wonder how many selected Brave just because it's at the top of the list and thought that this must be a good choice then, not because they actually like Brave.
It's nice to have such a thing for browsers, but it would have to be expanded to other apps as well, e.g. mail client. Oh well, maybe in another 10 years or so.
3,000 people clicked a button out of curiosity or by mistake. If this is statistically relevant for their install base, there really is nobody using Brave. I have as many users randomly come and go into my game on a daily basis.
Competition is healthy for a market, this is proof that people aren't happy with the default browser and it'll hopefully spur apple into improving their browser and in turn causing brave to improve even more
There is zero reason to switch browsers on iOS, They all run the same engine.
Safari also has extensions (which I believe 3rd party browsers can't use).
