If websites want my business they’ll support my browser.

Sure, but that goes both ways, which is the part where you start losing a lot of privacy evangelists and Firefox fans. You are entitled to full control over your device and browsing experience, and sites retain the right to block browsers interfering with ads, trackers, or whatever else the sites use to pay the bills. A lot of people want it both ways and that cannot work at scale.
