It seems to me that the plane-based altimeter hardware here is incredibly antiquated; honestly, it seems incredibly vulnerable to jamming and attack scenarios, not just interference from 5G.

Now, it's reasonable for aircraft manufacturers to say "hey, in the absence of guidance, we haven't had the time to improve this hardware, let's ensure that the replacement timetable and the 5G rollout timetable in landing pathways are well coordinated." And if guidance is indeed absent, that's an incredible failure on the part of regulators, and one we should hold them to task for.

But it's another thing entirely to try to say "5G around airports should be restricted indefinitely." The OP article doesn't give enough detail to determine what it actually is that manufacturers are proposing, but one imagines that if a timeline were specified in their proposal, one reasonable enough for the manufacturers to publicize, it would have been reported on.
