I can't confirm. All claims are real.

I have full control over my funds with the internal LDK based node and I also got the seed and channel backups.

I can connect with any NWC enabled app and use my albyhub as wallet in these apps.

Albyhub does not require an alby Account at all. But it has some benefits which don't compromise on decentralization

In my opinion Albyhub is the best solution to run your own lightning node in the cloud or on you own computer. I use it for my friends and family and also have stackernews connect to it.
