I heard the term GPL leakage mentioned very recently in a presentation from a well qualified speaker from MongoDB at an event for developers & integrators in the cloud computing market. I've never heard this term anywhere else, but the audience seemed to follow what he was saying, suggesting this might be an institutional issue.
The context was that cloud computing providers might be providing database implementations to include MongoDB (itself open source, AGPL v3.0) as well as their own software. I can imagine some of the legal implications of this, but only vaguely... so would appreciate generally what's meant by this term and/or whatever institutional problem it suggests: preferably with an example.
mongodb gpl derivative work
which turns up the popular thread AGPL - what you can do and what you can't with a lot more background info, including a link MongoDB: The AGPL which details the solution the speaker could have been suggesting. – rphair Jun 15 '16 at 14:42
