I don't think that's actually the case...the network has always held most of the high cards in any affiliation agreement, and if anything that's even more true now than it was decades ago when the Central NY TV landscape took shape. I once worked for WTVH's former radio sister station, WHEN, when both were headquartered in the Channel 5 building at 980 James St....Channel 5 had no special claim to the Utica market, just wound up as the closest CBS affiliate (45 air miles from the Sentinel Heights tower to downtown Utica) pretty much by default.

Again, the affiliation rights would only cover the Syracuse ADI which doesn't include Oneida County.

Watertown had no TV allocations at all until the 1952 re-writing of the TV allocation table. The FCC divided up station allocations in '52 based on a combination of technical issues and market size, and made several mistakes (most notably giving Rochester, Syracuse and Albany too few stations) that it had to correct by reshuffling the deck and changing the allocation table in markets along the Thruway between Buffalo and the Hudson River. Utica and Watertown didn't pick up any more allocations in the shuffle, though when they rewrote the table in 1958, WKTV in Utica had to move from 13 to 2, and WROC in Rochester and WHEN in Syracuse to do a straight channel swap (5 to 8 in Rochester, 8 to 5 in Syracuse), to allow Rochester and Syracuse to get an additional VHF station each and Albany/Schenectady/Troy to get two more Vs, all of which were on the air by the fall of 1962.
The lack of a presence of one or more networks in a small market is almost always a function of no one spending the money to build an affiliate, rather than the network's reluctance or lack of interest.
