WJLP's change from virtual channel 3 to virtual channel 33 (while remaining on real channel RF 3, VHF-Lo) may have very little impact on OTA viewers (other than the inconvenience of causing some remote controls to get "confused"), but it could have significant adverse impacts on WJLP's marketing strategy.
If the cable companies decide to put WJLP into a slot that is far removed from the other broadcast channels, such as WCBS (virtual 2) and WNBC (virtual 4), that could cause cable TV viewers to run across WJLP less frequently while channel surfing. It would also send the message that WJLP is being deemed unworthy of a plum slot.
But, cable TV may go down the drain soon anyway. Who has money to be paying the high prices the cable companies want nowadays?
