But this is exactly the problem. If Chrome had only 25% market share they wouldn't feel that they could force users to use Chrome. But if Chrome and Safari make up 80% of the browser market they feel like they can.

Chromeium based browsers have more like 95% of the market share. Look in this thread; every little thing Mozilla does is treated like the end of the world and a severe breach of trust. Google literally says "Everyone should implement this brand new proposal that makes being truly anonymous on the web impossible" and it's fucking crickets in their usage numbers.
