The Anti-Lambo
I really don't think it's that big a thing. Keep in mind this mic has been around since the 60s, as far as I know.
There's a huge list of electronic equipment known to suffer from the foam degrading or, worse yet, turning to sticky goo!
Microphones, mixers, synthesisers...
I had an RE20 capsule replaced for free by Electrovoice not that long ago under their lifetime warranty.
This was a second hand microphone...They didn't even ask!
Those things are built like tanks. After the nuclear holocaust there will be nothing left but cockroaches and RE20s.

(Who knows, maybe they the got that down too.
