Why cut off the iPad 1

I was a reader of this magazine until they decided to cut off iPad 1 users from getting the newer magazines by requiring ios6. Why do that? The first iPad is still widely used and had no trouble displaying these magazines. Boy am I glad I bought the magazines on a one at a time bases instead of subscribing. I was not aware this publication was the kind to turn around and stab their loyal readers in the back.
