With their original comment,

If they make it difficult or impossible to acquire through purchase (false scarcity by removal fro market) or if despite purchasing a physical object, say a car, I can’t fully use it or repair it without special software I think an argument can be made for surfing the high seas.

I'm only talking about the first case of the or here. I specifically pointed out the other case that you are referring to was not something I had an issue with.

Edit: And how does this change anything? Companies aren't any more obligated to sell people things than individuals. There are instances where it may be beneficial for a company to choose not to sell certain products, for example if a better product exists that should succeed the old product or when a certain product is later discovered to be harmful in some way.
