In particular, it's easy to inspect the sources for apt packages using "apt-get source". Snap seems to have no equivalent command.
Sure because Snap is designed to be able to distribute closed source applications. Part of the reason Snap and Flatpak exist is that distributing binaries on Linux is an enormous pain.
