I guess I just don't buy it completely. Given that I myself have had a hard time giving permission to Flatpak to access even an unimportant network drive (Flatseal is a godsend for giving/denying permissions in any way you please) while the same app on windows will happily write anything to C:\Windows\System32 , I feel like we're talking about entirely different beasts. But perhaps I'm naive. I also feel like there would be a very large vested interest in making people feel more unsafe in linux than they do in Windows/MacOS for obvious reasons.
And given that the version of Fedora I use is immutable and even I have a hard time messing with it to the point of pain/exploit with full access to the system (and I've tried for fun in VMs) I feel like a trusted flatpak app I download from a trusted source is going to have a damn near impossible time doing much of anything. While I feel like a simple website hack that serves me a bad .exe could/would cripple every single file it can find on my network on a Windows machine.
