Pretty sure Chromium based edge does not sync to google
> The reasoning given for this change? Google does not want users to be able to "access their personal Chrome Sync data (such as bookmarks) ... with a non-Google, Chromium-based browser.
I actually use this for having one google profile running in two browsers on one computer (one with a proxy, one without).
Sucks quite a bit as this is the primary sync system for Chromium. You can run your own but that is not quite that nice.
Didn't Microsoft replace all Google APIs with its own alternatives? This change probably will have bigger impact for other browsers built on Chromium, like Brave, Opera, Vivaldi etc.
Edit: I guess maybe not.
