Does anyone know how much profit can be made from that browser?

I don't think it's enough to get you to use a site, it's more like a bitcoin facets, right?

And then what is the development that this browser does, all the good features can be done with a small team of developers,
Just block ads is the unique feature that they offer, the rest of the things are a compilation of some features.
I think they want to achieve profits quickly and the last thing that matters to them is the protection of privacy.

will remove it.
