Comcast streaming limited to home network?

 I used to be able to stream live TV from my account at any network location.  Now I get a message says I have to be on my home network.  Why is this new limitation?  The pop up says it is due to licensing, however, it appeares to be a way to sell streaming for $20 a month.  This a major reduction in service, and a significant cost increase to get streaming back.
