> Do you buy music on iTunes?
That's like asking HN if they buy Christmas CDs at Tesco. This is a very self-selecting group of people. I know people who buy off of iTunes, who don't use Spotify, who've never heard of Bandcamp, who still listen to the radio… there are people beyond your little bubble. It's a big old world.
I do try to stick with Bandcamp, but a few bands I want just don’t use it.

You're re-arguing their point. They are saying it's such a diverse market that iTunes doesn't effectively act as a proxy for the whole market anymore, not that no one shops there anymore (shades of "No one goes there anymore... It's too crowded!").
