If it’s not theft, why does the greed and unfair practices of the industry matter?

Because it tears at the fabric of Humanity. It’s a ‘death by a thousand cuts’.

Humanity constantly needing to be on guard and pushing back against being taken advantage of by people who want to charge them multiple times for the same thing in different ways, especially the ones that used to be free, over and over again.

Fighting that is pushing back against unfairness, which is one of the root beliefs of Humanity.
