I think blaming people who are trying to make a buck using the fastest route is not the way to achieve non-monopoly.
A practical point: Mozilla made design choices in the past that made it harder to hide the automation footprint. For some time it was more difficult to disable the navigator.webdriver flag in Firefox compared to Chromium.
That's why we support Brave, Edge, Ungoogled-Chromium, and our own custom Chromium fork that we're working on.
Just because we only support Chromium doesn't mean we're pro-Google-dominance.
There are enough Chrome forks at this point that Google no longer has the power to unilaterally remove features from Chromium. Manifest v2 extensions still work great in Brave for example.
That's not really true, https://github.com/daijro/camoufox is at parity with patchright on stealth, it's just that Firefox has way less market share so it's not worth the >2x maintanance effort for us to support multiple browsers.
