Did I say it was illegal? Did I say it was legal? That's for your own determination...
You can buy quite a bit of content on iTunes, Amazon, Netflix, Hulu Plus, Vudu, Blockbuster, You Tube Movies, DVD Now and Red Box. Depending how much you spend on this stuff, keeping cable might be a cheaper option.
You could of course cut the cord and enjoy OTA-HD only, they show He-Man, She-Ra, Ghostbusters and Bravestar on a local channel here. A Channel Master DVR with Internet Apps cost $400, I know Fry's have them - http://www.channelmaster.com/Channel_Master_TV_s/304.htm
The truth is, whatever man. What's on HBO is available on disc. Amazon Ubox which can download content you pay for and put it in a folder that Windows Media Center can see gives you access to a ton of content for a small price. Netflix streaming is what $8? Hulu Plus is $10? The entire season one of the original Bionic Woman is $20 for the season, streamed/downloaded - http://www.amazon.com/gp/product/B004ML1IJA/ref=sr_1_2_vod_0_msg?ie=UTF8&qid=1340695068&sr=8-2
I'm still confounded by MTV, its not even a Music Channel anymore. That's why they started MTV2 and even that channel has less and less music on it... I sort of would watch Sucka Free, but its not that important.
