When I noticed Mr. Saganash's tweet about his Huffington Post article, I replied to say that while I didn't agree with everything he wrote about Bill C-11, I was glad he noted the harm to creators and owners from TPMs. I suspect it would be worthwhile for me to unpack that comment.
In a reply to Mr. Saganash, Jason J Kee disagreed with the suggestion that most countries don't prohibit circumvention for non-infringing purposes. I believe this reply conflates two very different types of technological protection measures included in Bill C-11: use controls, and access controls.
