Been there, done that. Back when I was a Novice (1953), hi-fi was the rage and everybody was buying amps and speakers. I was the only ham for about a half mile, so when Morse started coming out of their speakers, it was my fault. Actually, it could be argued that it was the amp makers fault, but a few caps on the speakers and all was well.

Jack,

The solution exists.? Implementation has work to be done.? Not because you want it solved?
but because from a pure technical stance its a problem to be fixed.? Some people like me
enjoy solving problems like this.?

The interim solution is external low pass filters.? ?Easy to do and moderate to low cost.

Since the discussion has occurred in a public place?and the issues known there can
be no intent, only a choice.? Is it a big deal?? I will not advise on how to proceed other
than a low pass filter externally solves it for now.? Just like the past, I still have 2 or 3
Johnson low pass filters for HF as it was the talisman against TVI and the answer
to the OO/FCC as well.??As is I only state the rule and do not aspire to be the umpire.?
However some ham down the block with a bug in their hat can write a letter to the
powers that be and the fun begins.? If "you, the collective, they" are not doing anything
the problem goes away but you (again the collective) know that a known problem
exists however trivial is not helping.?

Will it happen, likely not, least I really hope not.? ?But that is not a can't happen.
Hams still get blamed for the noise coming out of crappy computer speaker
and cable TVs? and the like.? ?I still remember the day 12 years ago I had
someone at the door complaining about his TV and speakers and saw the
tower (at that time all the sections were not up nor antennas) and it must be
me.? It was not, he had a CBer with an amp with a ground plane not high
maybe less than 50ft away obscured by trees. It was his neighbor.? I even
helped them both solve their problems.??
