> let's invent a "secure enterprise browser", because there's too much interoperability on the web

Enterprise browsers are an existing category, and even Google offers an enterprise version of Chrome.

The idea of an enterprise browser is that all of the interoperability that has been built has been between the desktop and web servers. Most desktop browsers don't have many features that allow an organization to manage them, beyond managed policies which honestly aren't that great. For the most part, standard desktop browsers are a big hole in both inbound and outbound security.

Enterprise Chrome is just regular Chrome with remote policy enforcement. It isn't a different browser.

From an engineering perspective, most browsers are "pretty much just Chrome(ium)", but that's not what I'm talking about here. The delivery mechanism isn't really relevant from a product perspective. It is a different product with a different price and different features.

Also, my point was just just say that there's a market for something like this. Chrome Enterprise is not even really that competitive of a product in the space.

For the most part, default Chrome and Firefox are designed primarily for B2C use cases.

Which is what Enterprises need. They don't need their own version of Chrome, they need to ability to make changes to it like force Proxy, insert MiTM certs and various other Enterprise stuff.
