Thats okay. They aren't selling life time though, but only raffle them away during promotions. So in this case they probably are sustainable, but the chance to get one is next to zero (unless you buy them off of someone else, as that is a thing proton supports).
I mean... how likely is it that the wallet just was stolen from the government. Unless there is a statement, I'd rather attribute this to incompetence than malignancy.
There is also a CLI without docker, for agent and hub, and you can mix & match. I can't say how well though, very happy with running it as docker compose.
There is no really config to speak of. You setup the hub. Then you click on add system and write in the IP. Then you click on "Copy compose". That is the agent you can then deploy with a compose file on any system. Click on add and it is there.
The only thing you might want to configure is alerting, but only once on the hub.
Meanwhile in Germany: we must ban (or place heavy restrictions on) everything from the internet that is potentially unsafe for the young ones. (Porn websites need to verify ID as well as games. Doesn't matter that no company outside Germany will do that.)
