Net neutrality is not a new concern, but has once again come into the spotlight with impending plans to roll back the net neutrality rules made under the Obama administration. A new Chrome extension aims to demonstrate just how bad that rollback could be.

Trying to explain net neutrality -- the idea that ISPs shouldn't be able to throttle your internet speeds or limit access to parts of the web based on the sites you're visiting -- is tough because it's often met with glassy-eyed stares. Now, rather than trying to explain, you can just show.

Chrome extension Removal of Net Neutrality Simulator shows users just what the internet would be like if the FCC really goes through with its plan to dismantle net neutrality as we know it.

Once you install the extension, you'll instantly see its effects. First, your internet will be significantly slower. Without net neutrality, ISPs would be free to throttle your internet speeds without restriction. With this extension, some sites are simply inaccessible. If you try to load Netflix, you're told to use Hulu instead. If you want to Google something, you're going to have to Bing it.

Of course, we don't know exactly what the internet would look like without net neutrality or how ISPs would take advantage of lifted restrictions. But this extension gives a "worst case scenario" experience, and it's a great way to raise awareness and get people to care about why net neutrality matters.

What do you think of this Removal of Net Neutrality simulator? Do you think we should be concerned about the FCC rolling back restrictions? Let us know in the comments.
