Good for Mint. Someone has to keep app and lib developers honest, not hiding behind packaging every app with its special-snowflake version of every dependency. (And I’m a developer, so I know it isn’t always easy to make an app robust against upstream version changes, but ignoring the reasons something might break can cause one to overlook possible errors or invalid assumptions in one’s own code.)
Tools to aid in mass-deployment are nice, but they shouldn’t be a crutch to hide overly-sensitive apps from their host OS’s valid version changes and updates. IMHO.
I understand your perspective, but i am very happy that all these isolation options exist.
All those companies saying that developing a Linux app is too complex can just shut up and build a Flatpak.
