> Are you saying that Apple doesn't support their customers well because they don't spend time writing software for 10 year old hardware?

This isn't even close to what he said, and it only makes sense if you have an extremely reductive black-and-white view of the world. There are places on the spectrum between "perfect support" and "absolute shit support", and the phrase "count against" simply implies that supporting decade old hardware is a notch higher than the same support setup without that advantage.
