F.OBN;
Again, thank you for engaging the question. I think discussion of this matter is important so that the salient issues can be discerned against a substantial background noise.
The salient issue is, as stated, that there are certain vulnerabilities to ACARS, ADS, (and also to GPS/SatCom, but that too, is old news; we've known about Satellite / GPS jammers for years). To me, the widespread (and growing) use of iPads for critical flight planning, weight-balance, enroute and approach-plate work represent a far, far greater security risk in terms of hackability with clear and safety-related results, than the present matter under discussion, but we'll stay on-topic.
The background noise is the inability of those proposing the notion that this is a serious problem, to articulate the means by which this is more than just an ACARS / ADS vulnerability issue which is, like the issues mentioned above, probably well known.
The presentation works because it implies much but says very little. We'll see where this all is in a week or so.
