> The problem is that radio altimeters are pretty old
Interestingly the 737-200 is excluded from this airworthiness directive. 737-200s are the oldest, still-operating members of the 737 family.

The entire aviation community has been aware of this issue and the manufacturers have been working on it.
It's not an exaggeration to say these things take time. "Move fast and break things" doesn't work well with aircraft.
Sure, but that didn’t seem to stop faulty lithium batteries on the 787 or MCAS on the 737-MAX. If only Boeing would learn the lesson, maybe we wouldn’t have these messes.
If anything, Boeing has been very proactive about identifying the affected equipment well before any accidents happen. This is precisely what they should be doing.
1) I never stated the radar issue was only Boeing’s “problem” previously, I stated it’s yet another example of a mess they are in which ultimately boils back to a “move fast and break things” attitude being a major cause (just in this case, it was more the FCC to blame for that attitude)
2) It ultimately is their problem to solve for the airframes they sold however, whether it was their fault or not.

Link to the ADs from Boeing saying which models are susceptible? I hadn’t seen that

As part of trying to keep flying safe, both attempts to limit sources of interference (i.e. 5G transmitters) and checks on existing hardware (and thus whether it needs to be replaced) are done in parallel. Outside of USA, everyone agreed on various mitigations to limit impact to radar altimeters especially as full impact of C-band 5G is still work in progress.
