For browsers, there is enough financial incentive for vendors: * Google builds a browser to control the market and make sure ads and their own websites are working well * Apple builds a browser to make sure web browsing on their devices is working well, uses little power and is not adversely affected by the competition * Mozilla is swimming in money obviously after all the previous Google payments So, money is not the issue with browsers - except that we could probably have a browser with built-in privacy (no tracking) and reliable ad blocking if users paid for it instead of large commercial entities. But that's very hypothetical (Google would buy that probably).
