Who disagrees with DIR and why?

every one that talks about donating their primary uses the example of a octo that do not work due to neglect ect. I do use my octo on every dive weekend. so I know it is working. the end result with giving a octo on long hose is the same as giving your priamary on long hose. If you want to assume toe octo is bad then I can assume your backup is bad and now their are 2 paniced divers as the first was out of air and took the only good air source from his buddie.
do I think this will happen. not if you dive with a buddie that takes care of their equipment. it comes down to haveing working gear and knowing your buddies level and experiance.
