sure. tell that to people who used the .af domains; or learn more about shenanigans with the various oceanian TLDs, or who owns the .io domain, and why.

the fact is that you don’t own the domain name, and it’s always one missed card payment (or registrar changing hands and losing your card data) from being lost, and then your best chance is arbitrage.

it’s one of these things that you have to understand when you start self-hosting anything.

you’ve never heard of a single example of anyone losing a domain due to legal maneuvering, trusting the wrong TLD (ie a bunch of lgbt folks losing their domains when the TLD’s administrating country decided not to give them service), or a plain ol registrar fuckup?

you’re far too inexperienced to be opining on self-hosting email, then

so what happens with the domain when the owner dies?

I’ve been using them for my domain and email for almost a year now and I have no complaints. I had to talk to customer support twice to fix a couple things that came up and they got back to me right away. Can’t say the same for the last service I used lol

I think it’s fair to point out they’re not designed around encryption like proton is. It’s not a factor in my threat model because I treat email as non-private communication, but it’s something you should know if you’re wanting proton for that reason.

kDrive is a heavily customized Nextcloud/OnlyOffice implementation with a pretty new and well-regarded file sync algorithm they implemented last year. I would recommend cryptomator to client side encrypt anything you want to protect. It’s at rest encrypted, but not end-to-end because there’s nothing client side.Here’s a list of WebDAV urls from the Cryptomator community to help you set it up. KDrive is on there.

Anyway, hope it works out for you!
