I think that's extremely ungenerous and misses the point of the article.

The article is specific in the mechanisms by which the industry has changed formulae -- adding air, gums, and stabilizers. It also includes information about who the offending companies are (Unilever). It includes information about how many calories per cup indicate a high quality ice cream, as well as the legally required labeling you can use to recognize not-quite-ice cream.

It also specifically addresses the "cream is expensive" concern, and discusses dairy prices which have fluctuated but not spiked.

No, this is greed and "the customer is a fool who won't notice". The products of capitalism run to a point where there's basically no recourse (short of, I suppose, manufacturing the ice cream yourself) because everything's become one giant megacorp who knows you don't really have much of a choice in brands.
