Encryption prohibition is only for amateur radio. Amateur operators can also use this portion of the spectrum (and with a power greater than one watt), but they must disable encryption and TX their callsign at fixed intervals.

There has been no push to make encryption unlawful within the ISM bands.

Your wifi uses encryption within an ISM band (at 2.4 and 5GHz).
