You are right.
I would prefer the formally correct "OpenPGP" after reading a bit more.
This is how it is named in the RFCs [1] and this is what we mean.

If we use either gpg or pgp it will raise new questions and confuse the 
users.

It is better to write 4 additional characters and make it simple and 
precise.

We can explain all details in the description then.
