One of the biggest benefits of Flatpaks is how it puts apps into a container. It allows apps to ship with all of their dependencies and keeps them from altering your system files to install themselves, which are fantastic benefits; however, I’d argue the best reason to use Flatpaks is the privacy and security angle. You can control what a Flatpak can and cannot do through apps such as Flatseal, so your apps can’t access files or devices if you don’t want them to.
