Mike Evangelist, a former director of video product marketing at Apple, is calling for a boycott of next-generation HD (high-definition) video products.

Evangelist is extremely angry, warning that the move to HD is being exploited by the video industry to eventually eradicate "the concept of fair use" of products.

"This is important," he wrote on his blog. "I really want you to understand what's going on with the video industry's push towards HD. They are engineering a complete removal of the concept of fair use. They are setting up systems that will completely control how, when and where you can use content that you buy. Even worse, they can retroactively change the rules!"

He warns that a new content protection system dreamt up by video industry heads will limit what consumers can do with the movies they own.

It also contains clauses under which manufacturers are agreeing to cease producing analogue devices – such as video recorders – after a certain time.

"The studios are salivating at the prospect of you never actually being able to own content again," he warns.

He's calling for a wholesale boycott of such products.
