I've heard about ISP's doing that (fortunately Charter hasn't started with that yet....the only good thing I can say about them), but I'm wondering how is it legal. You're paying for 13mbps down, and only getting 10% of that, which is 1.3mbps. I know 13 is merely a cap and speeds will never reach that high, but a difference of nearly 11mbps means you are NOT getting what you're paying for. I'm normally sickened by all these frivolous lawsuits, but I really hope someone starts a class action against these ISPs.
I know it's to stop illegal p2p, but that's not the ISP's responsibility, if people want to download, so be it. The proper authorities will go after them. Shouldn't be the ISP's job to babysit, especially since it does eventually affect 100% legal activities. It would be like buying a Bugatti that after 5 minutes automatically reduces its power output to 150 horsepower because speeding's illegal
