I mean, to put it simply it would just work with a digital mode. But that's not the point, the main point is that there is no authentication mechanism. Such systems are indeed being abused, for example trains were recently halted in Poland. This happened because they have an un-authenticated channel of communication that allows anyone to do that:

It's only a matter of time before this happens in aviation, but unlike in the trains case it doesn't have to be just an availability problem (all trains stopped safely), it can be a "remote code execution" problem.
