But in a slightly different domain, my broadband provider advertises "Unlimited XMbps broadband" but throttles after 1.5Gb. That's clearly not "Unlimited XMb/s" That's "1.5Gb XMb/s broadband with unlimited 300Kbps broadband". Yeah I know broadband speed is a big grey area, and they have all these getout clauses like service conditions etc etc, but when it comes right down to it the whole thing just feels like a advertising con.
Unlimited[1] Internet, at blazing fast Xmbps[2] speeds!
1: Subject to a cap, don't worry it's large[3]2: We did the math, and it's theoretically possible, but you can get 60% of this speed[5]
3: 'Large' being defined as 'we won't tell you how big it is, or what happens when you go over. Trust us.'
4: Only at 3am when nobody else is on, with a brand new computer, fresh install of Windows, speed determined by loading http://google.com/
5: Subject to interplanetary alignment, some other conditions may apply.[4]
Unfortunately, this makes it easier for them get away with the 'unlimited' designation, since they're no longer promising you any particular speed.
