I’ve never used Snapcraft, but I’m not sure where the criticism of Flatpak is coming from. If you don’t want to upgrade, then don’t. If you want to customize a particular package, all Flathub packages are available on Github and can be pushed to a custom repository. In terms of user control, it’s no worse nor better than the Linux packages that have been ubiquitous for a long time.
But the danger of developer being able to control updates from upstream will still be there with Flatpak, isn’t it? Such danger wasn’t present with apt/dnf/zypper.
