It’s not like I don’t use open source solutions, I use docker for example rather than automating chroots/cgroups by hand in bash. I just use them as little as possible. While you’re correct, I don’t lose data in a well designed open source project, I do lose work, workflow, and convenience when those projects change or shut down. What’s really nice about the pure bash solutions is they’re entirely portable once you have them dialed in. If I wanted to switch from docker back to vms or forward to something like harvester/rancher/k3s I’d be able to port the projects very trivially. If I built everything around one of those projects in mind, all of my work would rely on it not changing. I acknowledge it’s sometimes a little more work but it’s work that I get to decide when to do, not when the project maintainers decide it for me.
