Second, the FCC was already involved in their development and certification.
Third, these radars have been in operation for decades.
You are talking about thousands of planes that have to be modified to accommodate telcos. If anyone should pick up the tab for this it is Verizon and AT&T.
That makes their domination of spectrum far outside their range worse.
If anything, threaten to retroactively charge them for all that bandwidth.
Who cares? The comment you are responding to says "they did shoddy work on the altimeters." That doesn't mean that Boeing built the altimeters.
They specced them, procured, inspected, installed and sold it with the whole airplane. If the pilots' chair collapses, that's shoddy work on part of Boeing, and nobody would talk about how they are just buying the chairs from someone. Same with the radio altimeters.

Ok? Sometimes corners cut bite you in the backside only after decades.
There is one question which matters: Are the 5G towers transmitting on frequencies assigned to the use of radio altimeters or not? If they are they must stop. If the radio altimeters degrade or might degrade because of transmission outside of their assigned range and guard then they are faulty.
Perhaps Boeing should have bid of the spectrum that their products depend on being unused.
This is essentially the government leasing out previously unused federal land for mineral extraction and a nearby rancher saying "it ruins my view," only with safety concerns added in.
This spectrum can’t simultaneously be “unused” and a problem for radar altimeters.
