Does everyone nowadays only write software that is some messy desktop rendition of a website? The kind of software I write doesn't exist in a vacuum where all it needs is to run AMD64 code, Linux syscalls and a canvas to draw on. It needs to interact with the system, figure out what drives you have inserted, play nice with keychains and whatever.. You can't flatpak that.
