If people want encryption, they are welcome to use the ISM bands where it is allowed, or get licenses for the commercial areas of the spectrum.
But amateur radio is a public commons for those who have the interest in getting licensed, and encrypted comms being normalised damages that, making it less accessible to others and discouraging interaction between enthusiasts.
I fear that with encryption allowed, amateur radio will become a collection of competing 1-to-1 links and hidden commercial activity taking advantage of the cheap spectrum at everyone else's expense.
