Flatpak – a security nightmare
Cross-posting a comment from Reddit, because it nails one of the points mentioned:<p>---<p>The list on the page is<p><pre><code>    Gimp, VSCode, PyCharm, Octave, Inkscape, Steam, Audacity, VLC, ...
</code></pre>
With the exception of Steam all of those programs are used to open random files anywhere on the system. One could implement a permission prompt for accessing a file, but that would lead to a Vista-like Situation where basically every action causes a prompt.<p>Now, that's not to say this is good as it is, but for most listed programs it's probably the way to go.
