To put this into perspective: $100MM is 0.0759878% of AT&T's 2014 gross revenue, so less than 1/10th of 1%. That's like earning a $100,000/yr salary, and then paying a $75.99 fine. It's basically less than your average speeding ticket.
> $100MM is 0.0759878% of AT&T's 2014 gross revenue Which is completely irrelevant. To the extent a revenue comparison is relevant, the relevant revenue isn't AT&T's 2014 gross revenue, its the revenue over the period of the activities covered by the fine attributable either to the unlimited data plans, or to other data plans to which people switch from unlimited plans once the slowdown was in place.
If I cheat by committing a crime this year that saves me money, then continue earning more money each year from here out, all while squashing competitors, is the advantage I gained by cheating this year no longer relevant in 5 years?
