I talked to several AT&T CSR's about this yesterday.  I was told that it is all true and that if I want data, I have to spend a great deal more than I am now. Hence I will be gone when my current airtime expires on 4/20.  

After I talked to one CSR, who told me that it is all true and gave me detail, I called again and talked to one who had no idea that this is happening and he didn't believe me.  That tells us that AT&T CSR's are very poorly trained.  What a pathetic company.
