For the time being.
The rules of net neutrality are once again in effect for the United States. That rule was overturned by the courts in early 2014, forcing the Federal Communications Commission to pass that law through a number of legal hoops.
Net neutrality allows the Federal Communications Commission to stop Internet service providers from tampering with your service for unfair reasons, such as throttle traffic speeds or blocking access to specific websites.
Greedy Internet providers will no doubt take the Federal Communications Commission back to court in an attempt to overturn that ruling.
That's one of the many reasons why I've stuck with Hawaiian Telcom all these years. They've never throttled my Internet speed despite using upwards of 1 TB of bandwidth monthly!
