Switching providers or to the competition is a fallacy since most places don't have any competition anymore thanks for franchise agreements, or at best a duopoly especially in the US. To REALLY "switch" people have to be willing and able to move and to invest in places that do have good broadband infrastructure and to ignore and economically affect those that do not. Supporting municipal networks, Google Fiber, and Sonic type projects and stop giving money to providers who cap. Aside from that property values, business investment, even tax dollars. These are now our weapons. The US is lucky enough to still have a private sector and local govts who have the means to build alternative networks. This is a luxury that many other countries like Canada do not. Support it and nurture it. Do not let these bastards win.
Others in the fight.
