I would really like for him to go into detail into why Flatpak is flawed from day one, or his MAC criticisms. Fedora has a lot done on the former and no mention of it.
Also why not recognize the strides Wayland made for security in the desktop? Very handwavey take.
It's pretty ironic that he first laudes macOS so much, disparages Linux for having strong NIH, but then hates on systemd which is heavily heavily inspired on macOS.
And yeah, I don't understand his hate on Flatpak unless he means the sandbox is too user-hostile. So many things break with Flatpaks, from native messaging hosts (think browser extension talking to desktop application) to theming to local folder access to pasting from the buffer.. it's quite a draconian sandbox.
