What would this business model be like, if, say, Google Chrome is eliminated?

As a reference, in China, very few people use Chrome because Google services are blocked. There are tons of third-party or vendor preinstalled browsers that bundles with bloatwares, put ads/clickbaits on every new tab, and spy on users. I'm pretty sure they are more sustainable than Firefox, former Opera, etc. But that's certainly a privacy dystopia :)
