Yeah, this kind of thing shouldn't be taken lightly. With no net neutrality, ISPs could legally charge you extra for visiting certain websites. If they wanted to, they could make accessing the Blockland Forums cost an additional $5 a month, and it'd be perfectly legal.
As I recall, Annoying Orange's pick for FCC head has publicly and repeatedly stated his intentions of scrapping net neutrality. Prepare for the internet to become like cable TV, where everything is divvied up into packages and options and ends up costing a fortune for full access.
