This situation could last for some time. The seed for this fiasco was planted long ago in Toledo TV history and an FCC policy called "significantly viewed".
In this case, Buckeye is not under great pressure because dropping WUPW does not mean viewers lose Fox. Buckeye subscribers are getting Fox on cable 52, WJBK Detroit.
Toledoans have been watching Detroit TV for more than half a century. For ten years, Toledo had only one TV station (channel 13), whilst Detroit had four (five if Windsor is included 1954 and later).
This so affected viewing habits that it shaped the Toledo stations as well. All would eventually place their transmitters east of town, right up against Lake Erie. This is a stupid place to put them, as much of their signals are wasted over the lake, and overlapping the coverage of the Detroit stations, while places like Findlay have poor TV service. They had to put them there, because everyone's antennas were pointed at Detroit, and placing the transmitters in a more sensible location (e.g., near Bowling Green) would have resulted in ghosty reception in Toledo.
Now, remember that, or decades, Detroit had CBS on channel 2, NBC on 4, ABC on 7, a Canadian partial CBC affiliate on 9, and, from 1965, an independent on 50. All of these stations were given the "Significantly viewed" badge (see "Significantly viewed out of market TV stations in the United States" on Wikipedia), meaning that Buckeye can carry these stations, even though they are in another market.
Then, in 1994, there was the affiliation switch (Detroit was only one of several markets in this multi-year event), and 2 changed from CBS to Fox. Thus, Buckeye (and other Toledo-area cable systems) carry WJBK.
This situation could last until the time comes that Buckeye will have to renew their carriage agreement with WTOL. WTOL will probably demand that Buckeye carry WUPW (at a premium) along with WTOL. Buckeye will not be able to substitute Detroit's CBS station for WTOL. WWJ is not a "significantly viewed" station, because WGPR channel 62 was a black-owned independent with a poor signal in Toledo when the SV policy was being crafted. WTOL will have the upper hand unless Buckeye could convince CBS to abandon WTOL as their Toledo affiliate, allowing Buckeye to pick up "CBS 38", "40.2", or whoever. Buckeye has such penetration of the NW Ohio market that they may or may not be able to pull that off.
