Nope. AGPLv3 is very different from GPLv2. Also the wishes of the creators of Linux and git make the GPLv2 more comfortable to me. Companies that have a dual-licensing model with GPLv2 and a paid proprietary license may try to stretch the meaning of the GPLv2 to make it more restrictive.

The problem with oauth.io is I could spend time learning it to use it on a personal project and then not be able to apply the same knowldege on a client project where the client doesn't find the copyleft situation acceptable.
