You know what's horrifying about the idea of "just fork Chrome"? Google can still hurt you by blocking your browser's access to their prime properties (YouTube, Gmail, Maps, etc). Just look at YouTube denying Chromium-based Edge the new redesigned experience for absolutely zero reason.
> Just look at YouTube denying Chromium-based Edge the new redesigned experience for absolutely zero reason. The reason is almost certainly a new user agent (compared to non-Chromium Edge) that YouTube didn't expect. Chromium-based Edge is still not stable, and therefore, not properly supported by YouTube. I don't have time to test this, but I'm willing to bet that you'd get the same result by using any indie browser…
The web is a standard. Auto failing based on user agent is a sign of developer incompetence.
