> Startups should do things in order.

It's a browser company. What do you mean, "order", do they have other priorities other than creating a browser?

Creating a browser engine from scratch is no easy task. Knowing this, why not use a quality browser such as Chromium as a base and build on it? Their goal and priority are to change the advertising and monetization of the web, not build another engine that would take years and millions of dollars to make.

All the other stuff they're working on that's more important than creating a new engine.
