Unlikely to happen because:
- Writing a sync service from 0 is a gigantic pain
- Akonadi is incredibly powerful and handles most of what anyone would need from a sync service
- Akonadi has a sensible and easy-to-use API that apps like Kalendar can leverage
- There is no alternative that uses KDE APIs that is under active maintenance
Not saying Akonadi doesn't have big issues, but it is a good base. It just needs more love -- love it hasn't really gotten!
Most of that money goes to paying for contractors and events hosted by the community. AFAIK there are no contractors being employed to work on Akonadi. Like 99% of other KDE developers, Akonadi developers do it for free.
Paying someone to help improve the framework would be one way to help things. The other would be to try to encourage new developers to come in and help -- this is what is mostly done for other KDE projects like Plasma.
