What's corporate slop
Do i really need to iterate the shenanigans of canonical?
Flatpaks support drag and drop just fine. I think you're confused?
I once installed discord as a flatpak and couldn't drag and drop files. Installed the .deb and it worked perfectly fine. I also had a lot of file permissions issues with flatpaks. I now avoid them like the plague.
The same thing Ubuntu does: reliability
And how is mint less reliable? Because it has less maintainers? So if you have a billion maintainers, then it should be more reliable? Right? Totally wont be a spaghetti mess. Unless you can actually provide metrics... we can assume windows is more reliable for having thousands of highly paid developers... by your own logic.
