that website is such a joke, I can’t believe the guy’s still paying for the domain name… The whole argument boils down to “Many flatpak apps don’t make use of the sandbox by default, which is <somehow> less secure than not having a sandbox at all” and “this one app I like doesn’t work in flatpak, therefore all of it is bad”.
…unless it literally is a joke and I’m just missing out on the sarcasm?
