It looks like the U.S. trademark for "PRETTY GOOD PRIVACY" (Registration Number 2015027) has "Cancellation Date April 24, 2020" even though the one for "PGP" (Registration Number 1914615 - with the identical "computer programs for data communications applications, and for the encryption and authentication of electronic information" description) isn't canceled.
Was this relevant to making the "likelihood of confusion" low enough that there's no risk of needing to rename the Pretty Good Phone Privacy product?
