As long as these apps have been properly approved for distribution via Apple's App Store, I don't see a problem with Apple devices having a folder with a few legally required apps pre-installed in it, with it being easy for the customer to uninstall/remove them.
Or maybe even just make installing them part of the first-time user set up... one of the questions will be "Do you want your national apps installed? They can be easily installed later and are not required for your device to function properly."
That is how it should work in the real world but sadly Russia is not part of the real world under Putin.
