Directory themes and licences


This question has probably been asked, i did a search but couldn’t find the answer…

If I buy a “Directory” Theme and use the paid subscription options which most of these types of theme include, and charge the end user a membership fee for having a listing on the site, do i need to buy an extended license?

Its not clear from the license FAQ section which just states that if end users are charge to view content, extended license is needed,

Any clarification?
