In general only network O&Os and station groups that also own Big 4 affiliates opt for retransmission consent payments, everyone else usually opts for free must carry status. Class A and LPTV stations can't opt for free must carry status, only full power stations can, and it only forces carriage of their primary channel. The offer to negotiate carriage to one, offer to negotiate carriage to all rule for stations that opt for retransmission consent payments only applies to the primary feed of full power stations, offering carriage of subchannels is optional.
Both DISH and DIRECTV tend to only carry subchannels and Class A/LPTV stations if they are the market's Big 6 affiliate, or in select markets, the local Univision, Telemundo or UniMas affiliate. For some Gray owned stations that results in the MeTV subchannel being carried because they pre-empt 2 hours overnight to clear MyNetworkTV, in some other markets that results in diginets like DABL or TBD being carried.
In some cases the diginet affiliation agreement even specifically states the subchannel affiliate only has the right to negotiate carriage on cable and telco providers, so the network can seek a national deal with satellite and streaming providers.
Dish did not black it out here in Indy.
Indy's MeTV is WTHR 13.3 along with a simulcast on their Class A sister station WALV-CD 46.1, neither of which are carried by DISH, so the national feed wasn't blacked out for you. DISH blacked it out in markets like NYC, Denver and Philly where their MeTV is carried as a local channel, and DIRECTV does the same.
As for Vegas, even though KHSV is a full power station, it's owned by one of Sinclair's shell companies Howard Stirk who "voluntarily" withdrew their satellite carriage and reduced their cable penetration to eliminate themselves as local competition after its major network affiliations and syndicated programming were moved to the station Sinclair outright owns as part of their ownership cap loophole shenanigans, so DISH was still able to offer MeTV's national feed in the market and DIRECTV is able to offer it too. (At around the same time in 2014, Sinclair made similar moves in Birmingham, Harrisburg and Charleston and they have since done it in additional markets like Dayton)
