Linux users have platforms like Flatpak that sandbox applications to known directories, and have multiple "app store"-like implementations with colorful buttons to make the process look unintimidating and non-threatening. Another option is to simply use distro packages. Users of good distros who use distro packages have software that's vetted built from source independently, and compatible with the rest of the system.
