An expert hired by Charter Communications to offer “qualified” views on the competitive impact of a merger involving Charter, Bright House Networks, and Time Warner Cable got his facts wrong about Charter’s data cap policy, a mistake that calls into question his analysis about the company’s potential to abuse broadband customers by imposing data caps after its three-year commitment not to expires.

Theodore Nierenberg, a professor of economics at the Yale School of Management, among other things, offered an expansive rebuttal to opponents of the Charter merger deal, arguing that it would enhance competition and deliver consumers enhanced benefits.

Nierenberg does not believe Charter has any interest in imposing data caps on customers, despite the fact Charter quietly shelved existing caps on Oct. 1, 2014, several months before unveiling a bid for both Time Warner and Bright House, neither of which have capped customer usage.

“I conclude that actions such as charging interconnection fees, imposing usage based billing or data caps, or degrading network performance are very unlikely, both because New Charter has no incentive to undertake them, and because the FCC will enforce New Charter’s commitments,” Nierenberg wrote.

But his facts are in error. The same company that believed usage caps were an essential part of its broadband service between early 2009 until October 2014 has suddenly turned over a new leaf? Nierenberg claims there was effectively no leaf to turn, claiming Charter had no “active data cap” since January 2012¹:

For 3 years, New Charter will not charge consumers additional fees to use specific third-party Internet applications, or engage in zero-rating (discriminatory exemptions from a data cap).

These binding commitments provide further assurance beyond the economic reasoning I describe below — assurance that New Charter will not engage in these types of conduct: charging higher interconnection fees, using discriminatory data plans, or reducing the quality of OVD signals. (Note that Charter already does not have data caps for its residential broadband customers. Notwithstanding the dramatic but welcome rise in data usage by broadband customers, Charter has not had an active data cap since January 2012.)

Customers in some areas were called by Charter for exceeding their usage allowance, and usage rationing remained a fact of life in Charter’s Acceptable Use Policy until late last year, not January 2012 as Nierenberg claims.

So what assurance should a customer take from a company that believed strongly in usage caps for more than five years? Surely not that Charter will never consider engaging in data capping yet again three years from now.

Charter can assure consumers of its good intentions by declaring it will always offer affordable unlimited access Internet without a three-year expiration date. Quietly dropping a cap several months before executing a well-planned buy of Time Warner Cable and Bright House doesn’t inspire confidence. Too often short term rate freezes are followed by accelerated rate hikes once the deal conditions expire.
