In reply to Matt.

Hi Matt,

Thanks we'll certainly review our wording.

We are in a unique position where we will support any user who uses Layers, regardless if they use Layers Pro, a 3rd party theme or extension, so we cannot guarantee that support would be limited, in fact we would never limit support.

When we sold Layer Pro on Envato, regardless of what GPL says, advanced users felt (perhaps by good will) obliged to purchase "1 copy at a time", therefore it was by popular demand which brought us to the decision to introduce more license options, as users felt that paying $35 every time they wanted to use Layers Pro on a site was not viable.

I think it's also important to note that users who are buying multi-domain are advanced users and often times choose to pay more for higher usage regardless if there are limitations or not.
