This is actually a good thing. People shouldn't be syncing ANYTHING with google :)
it's a bad thing. Most users are going to ditch chromium for chrome which is precisely why Google is doing it. A browser without cross device sync is not going to have a meaningful audience.
Isn't Chromium exactly Chrome minus Google extras? I was under the impression that the difference between the two was exactly said Google-specific features that were apparently only cut off now.
There's still Google features in Chromium, just not the features google doesn't want anyone looking at the source of.
Here's a fork of chromium with the other google bits removed. https://github.com/Eloston/ungoogled-chromium
