Brave seems silly theoretically for two reasons:

1) I think it's well established (or perhaps not well established enough) that "non-profit" is the only way to go for base level computing things like this. Profit motive (as distinguishable from "keep the lights on money," e.g. with Wikipedia) makes you do unnecessary and often harmful experimentation.

2) It's a fork of the thing you're trying to beat. Now, that may not be a deal-killer, but given Chrome's dominance, getting outside of that entirely seems smarter.
