Zap2It's TV Listings Are Gone

Apparently, within the last day, Zap2It's TV listing site is gone - it now directs to a NewsNation schedule (which nobody wants!).
For now, it seems to still exist on Gracenote:
https://tvlistings.gracenote.com/grid-affiliates.html?aid=lat
But who knows how long this will last...
FTR, TitanTV's guide also still exists:
https://www.titantv.com/
But they're another one that I wonder how much longer they can survive...
So, are we soon heading to a time when online TV schedule guides no longer exist?!!...
