They just throttled it just of the blue? There was a probably a high demand for that content, just like if there are too many vehicles on the road you are gonna get traffic stops. What NN is just gonna do is stop telecoms from enabling you to buy a "lane" for that content so you can enjoy it without throttling, they are mostly not interested in stopping you from consuming any content and having free speech on the Internet, while goverment certanly is.
