Only because a project is serious about actually publishing vulnerability data does not make it necessarily more insecure (or secure).

In the case of Seafile one could simply change passwords of any user etc.
But yes, crypto is hard and I agree that the way we did it at ownCloud is far away from the best way. :-)
Yes, there's FUSE, but I still prefer the way Owncloud handles my files.
