Another competitor has spoken up against the proposed Comcast-Time Warner Cable merger, and this time they went to the feds.
Satellite television provider DISH Network filed a formal petition to the Federal Communications Commission (FCC) to block the merger, citing "irreparable harm" to the industry and consumers.

Among the "significant" potential harms that DISH identified in the merger are "discriminatory data caps," and "restriction of third-party online rights" stemming from the large market share of a successfully merged company.
"Here, the public interest benefits [Comcast and Time Warner Cable] claim are unlikely and speculative. Further, the claimed benefits do not come close to outweighing the anti-competitive effects of the transaction, and the serious damage that will be inflicted on consumers if the merger is approved," the company said in its petition.
For its part, Comcast has repeatedly argued that a merger with Time Warner Cable would spur industry innovation rather than stifle it.
Disclosure: Comcast is the owner of NBCUniversal, the parent company of CNBC and CNBC.com.
