It really is a good idea, IMO, won’t hurt to have one.
According to Canon Rumors, there is/was a Canon Service Notice for the EF 24-105 II Lens. Here’s the link for more info, details if you own the lens. http://www.canonrumors.com/service-notice-for-the-canon-ef-24-105mm-f4l-is-ii/
I never noticed it was gone, ha. According to their blog post, Flickr is now has their Pro service back. Here’s the post: http://blog.flickr.net/en/2015/07/23/hey-there-flickr-pro-nice-to-see-you-again
Canon Professional Services changes. Have a look: http://www.cps.usa.canon.com/misc/cps_program_notice.html
I really hate it when crap like this happen. No organization should be able to take ANYTHING from people. Didn’t they learn from Instagram? Sigh…I’m gonna miss the facebook games if this ends up going through…
