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.
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).
