I have a wiki with Creative Commons content – now I wonder if I can legaly use Twitter Cards.
The Twitter Terms of Service state:
By submitting, posting or displaying Content on or through the Services, you grant us a worldwide, non-exclusive, royalty-free license (with the right to sublicense) to use, copy, reproduce, process, adapt, modify, publish, transmit, display and distribute such Content in any and all media or distribution methods (now known or later developed).
This does contradict most Creative Commons licenses, which require that at least the attribution is kept together with the distribution. Do the above terms apply to Twitter Cards as well? Is there a way to keep a license plate together with a twitter card?
