This wasn't Aereo's business (and yeah, they're dead).

Dish has carriage agreements and pays retransmission fee's to the networks they carry via this service. This is directly contrary to Aereo's model. Aereo retransmitted over-the-air broadcast tv with individual subscriber antenna's and tried to skirt retransmission fees so they paid nothing to the content provider (I honestly thought they should have won their case).

At some point Aereo claimed that they wanted to relaunch as an online cable company if they have anything left after bankruptcy.

A crucial aspect in Aereo's case is that their original business model (which was ruled illegal by the Supreme Court) paid nothing to TV stations, but under the new FCC MVPD rules they would probably have to pay retransmission fees to local TV stations, which would cut into their margins.
