The subhead is less sensationally figurative, but still has factual problems: this "one customer's discounts necessarily push rates up for others" is not strongly supported by the article, or by economic reasoning. (Often scale can drive everyone's rates down: that's the whole mechanism of utility monopolies!) And it's certainly not supported in the inflammatory "everyone else" formulation. And even in the particular leading anecdote of the article, it's not so much Amazon's rates that have caused a regulator to approve a new assessment on other customers - it's neighbors' demands for more-expensive underground transmission lines. Even if Amazon received no discounts, the lines would still be needed, and the regulator would allow this sort of capital outlay to be passed-through to ratepayers.
