This bill was under discussion for 3 years. Every year the JCP keeps proposing new and different changes. After all this if you have 81/99 amendments, you have to question if it is nitpicking and stalling, especially when you have things like the Finance Bill and Farm Bill that get passed in record time.
This seems like a political decision more than anything. There is also the fact that the industry does not like this bill at all, there are some powerful corporations who entered the digital consumer space recently and would be seriously inconvenienced by this move.
