The case by noyb referenced single player games. Stuff like session start, duration et cetera was being tracked.
I was one of the people that signed the SKG initiative after The Crew was taken offline. Not because I loved the game so much but it’s the principle. I payed for it and should still be able to play it.
Containerized software. The main advantage of this is that every application, or stack of applications, runs in its own ecosystem. You can restart a container whenever without having to reboot your entire system. You can store all data off a container in a volume, so if you hit a snag, you can recreate the container without actually losing any of your configs.
You can also create networks so that apps run in different subnets than other apps.
Very simply put, a docker container is like a mini system that runs on your main system.
Something else I like about docker is docker compose. You can create a container or stack of containers with a single simple YAML file without actually having to install anything yourself. I manage my containers in Portainer.
