This isn't much different that what both Windows and macOS do whem trying to scare users into using app store software only. Macs use some rather scary language (scary when you are not a "computer person") to dissuade people from installing binaries from outside of the app store ecosystem. Microsoft does the same thing, even worse if you have one of their Windows 10S versions which locks you to app store software only.
