In my opinion this is not or should not be about DRM it's insignificant really, it's about eliminating the competition known as FREE OVER THE AIR TV.          
I go back to the mid to latter eighties when we first received cable TV!!   Reasonable monthly cost, a few channels (maybe 20)! 
Then greed over!  When we dropped cable (cut the cord) approx. 10 to 12 years ago, we were paying a few $$ short of $200/mo.  We probably were getting 300 plus channels with many many many commercials AND they were also able to collect a service fee!!
We don't need 4K TV, can't tell the difference between 480 or 1080 as it is!  How much more internet bandwidth will be required or additional internet costs??  I will never pay for cable, satellite or internet that allow them to charge us a service fee and yet have unlimited commercials!!
