" I think it has most likely to do with RFI/EMI suppression"
THat would be my guess as well.
RFI/EMI noise is essentially always present and devices that work based on proximity to circuits are most likely affecting this somehow IMHO.
IF so, then the question becomes more about how this is done and is the approach more effective than other means that might cost much less, like use of Mu MEtal, etc.?
