If everyone who has high speed internet with the ISP’s that agreed to the Six Strikes scheme downgraded to the lowest speed, and made sure the ISP knew why, you’d see them either quickly dropping the Six Strikes crap, or adapting some other means of satisfying their Customers.
Nothing like a net profit decrease of a good 50%-75% to wake these idiots up.
And like i said, if it doesn’t work, people can unsubscribe from the service alltogether; it’s not like not having an Internet connection is the end of the world.
If everyone did that either the ISP dies, or adapts.

The fact that so few consumers REALLY understand just how much power they hold always baffles me to no end.
One well-organised protest run in which all their customers downgrade, and these ISP’s will be singing a VERY different tune, because having to fight a few lawsuits is nowhere near as bad financially as losing more than half of your net profit in the course of a few weeks.
Their shareholders would be in an uproar faster than you can say ‘supercalifragilisticexpialidocious’, because ‘MONEY !!11!1!’, and they would demand some sort of action be taken to safeguard their lawfull profiteering over that of the MAFIAA.
