I have concerns.

Best privacy

What does "best" mean here? Privacy is binary: either something is private, and only you decide who has access to it, or it isn't.

and unbiased ad-blocking

Uh-oh. That's a red flag. When a company makes a big deal out of being unbiased about something that isn't inherently biased to begin with, I just automatically assume right-wing.

by default.

And how easy is it to change that default if you don't like it? Or if YouTube kills ad blocking in it? No thanks, I'd prefer it be an extension, thanks.

Handy features like native !bangs

Custom search with extra characters. Firefox has had it for over a decade, and Chrome has had it for a while too.

and split view.

Pretty sure this has been in several browsers recently, too.

No adware,

Thanks, that's...kind of the bare minimum in a browser?

no bloat,

Degoogled is already that for Chromium, if that's really what you want. There are several Firefox forks that pull out a bunch of stuff and make it leaner, too.

no noise.

Bold move disabling the sound API. Respect. /s

People-first

Which people? Ok, this is easy to say, but essentially meaningless.

and fully open source.

Isn't BSD a sharealike license? So they can't not. Still, props to them.

At the end of the day, I think I'd still prefer a Gecko browser, or Degoogled if I absolutely had to use Chromium.
