> People always talk about web browser monoculture and cheer on new entrants, yet no one seems to mind the os monoculture. We will all come out ahead if there are more viable OS out there to use.

3 main OSes vs 2 main browser engine for consumer to choose from?

Anyway the main issue with the Browser engine consolidation is that whoever owns the Browser engine, can make or break what goes in there. Just think about VSCode's current status with all the AI companies wanting to use it and make it their own product, while MSFT attempting to curtail it. At some point either MSFT decide it commit to FOSS on this one, or the multiple forks will have to reimplement some functionalities.
