I wonder if it would be feasible for e.g. Canonical to offer a free, hosted implementation of the Sync servers. The protocol is openly documented afaik, and there might already be efforts to implement an open server. It also has e2ee built-in. Of course then you might as well go off and use Firefox, Brave or Vivaldi, but it'd be an option nonetheless, if not quite an expensive one.
