GPG's goal is about privacy, while OpenSSL is more of a toolbox with most of the tools you need for anything crypto-related. I imagine those people need to control integrity of the software, to make sure it is deployed correctly on their servers and distributed securely to their clients and users, and OpenSSL has all they need for that. Privacy, OTOH, is unneeded because they are not (or rather much less) after their own or their users' privacy.
