I would have done the same thing by now, right down to the SNY, but my elderly father-in-law (also a Mets fan) lives with us and it's actually almost worth the extra expense not to have to teach him how to watch internet TV. We have tried over the years. Our other TVs are variously hooked up to Rokus, Firesticks, and Apple TVs. We hooked up an Apple TV to his screen, showed him how it worked, wrote out the instructions... and he never used it. I still pay for a landline (remember those?) for the same reason.
But I did just get the $15 credit from Spectrum. Woo hoo.
