I agree, and by no means is it a replacement, but https://syncthing.net is pretty damn interesting if you want to control your own data. https://www.syncany.org [now abandonded] was a cool twist on the idea using cloud storage in a secure way.

I've been using SyncThing for a few years now and I'm mildly surprised that it is not more popular.

Though every time they release a new major version it breaks compatibility with the older major versions and this happens quite often. They need to stop doing that if they want mainstream adoption.

I think SyncThing also has the wrong model for mainstream adoption: you have to fiddle with host keys that you need to add to every peer. Bittorrent/Resilio Sync's model of using shared RW/RO/encrypted keys per share is much more intuitive.

There seems to be one open source project that aims to implement Resilio Sync's model:
