This past weekend, several podcasters notified the media hosting company libsyn that their podcasts had been pulled from iTunes completely. The podcasters received only a general email message from Apple simply informing them of the fact.
Libsyn reports that Apple’s reasoning for the takedowns:
The offending podcasts album artwork included unauthorized Apple product imagery.
Many content creators were unaware that companies are required to defend their trademarks and takedown unauthorized uses of them.
