Using a 100% GPL or GPL-compatible license should be a standard for any WP directory or marketplace. If I were running it, it's not even a question I'd pose. I'd rather my directory completely fail than to allow people in who violate, if not the license itself, the principles of our open-source community.

Realistically, I think a 100% GPL license is a good thing. I, and I'm sure many others, would promote such a place.

At the same time, I don't think any of this has any bearing on the success of the directory.
