If you look at the fine print in the published "Guidelines for implementing Net Neutratily" [1] linked in the article you will see that there are 3 exceptions to the rule (a,b,c). Being "c" the one that should fear us most:
EXCEPTIONS
a) "comply with Union legislative acts (...)
-> meaning that a court order can change Net Neutrality, hmmm ok. b) preserve the integrity and security of the network, of services provided via that network, and of the terminal equipment of end-users;
-> meaning that in order to guarantee the security of the network Net Neutrality may be avoided. I'm so-so on this one. c) prevent impending network congestion and mitigate the effects of exceptional or temporary network congestion, provided that equivalent categories of traffic are treated equally.
-> Meaning that ISPs can throttle specific categories of traffic at their own will.This last one ruins the whole law. And this is not what me as European wanted. ISPs won :(
