I've been using Brave on mobile and my laptop (currently running Pop!_os) exclusively for about six months now, coming from Firefox. Your criticism isn't accurate, Brave doesn't insert ads into pages, it gives you the option of receiving ads in your notification stream. If you choose to allow the ads you are compensated with a small amount of a crypto currency, which you can opt to have automatically distributed to the participating sites you visit. Wikipedia, for example, is a participating site. These micropayments offer the only viable monetization alternative I'm aware of to charging for access, selling user data, or including advertising on your page. I've moved to using Brave exclusively because I want to live in a world where the web is free to access but my privacy is respected and my browser isn't crowded with ads.

Honestly several of these guys just want to promote 'break google up' every chance they get just because it makes them feel good - without understanding how bad the consequences would be.

What would the bad consequences be?

One example: The road from security to revenue is a bit windy. So suppose chrome gets a revenue crunch after getting spun off, and lays off a bunch of the security group. Well, it turns out that security group is actually handling security for ALL of the browsers, because security is expensive, and none of the browsers are really making money, and chrome is open source. So now you've got reduced security in all of the browsers. Whoops?

Sure, could happen. Or maybe more of the relevant players share the load, the way they do with the kernel.

Brave does not inject their own ads into websites.
