If Brave and Firefox are in the same league as Chrome for you your sleaze alarm is a very very bad guide to the modern world and seriously needs upgrading.
There are different levels of sleaze; I use firefox not chrome so don't try to put words into my mouth. While firefox may be a better choice than the other two, that's not saying much and Mozilla is very sleazy. If you don't see that, maybe you're acclimatized to it.

Rather than take such statements at face value, here's an example of one such instance that probably hurts its credibility: https://calpaterson.com/mozilla.html
Also, they're not exactly a world apart from Google in some respects either, for example: https://killedbymozilla.com/ vs https://killedbygoogle.com/ (though i guess the amount of projects also illustrates the difference in their sizes)
Personally, i think that we're past the peak of Firefox and are currently in the midst of it fading away, which i expect will come to its conclusion in the following decade. Apart from that, we basically have just a bunch of browsers that are all similar to Chromium.
Essentially, Chrome will have probably lived long enough to kill IE by becoming the next IE.
