I have an hbo account through verizon fios, and typically watch shows through hbo go. Its hbo's streaming answer to being able to view the content you already pay for. The service is terrible, it constantly stops buffering and looses its place in the show / movie and you have to restart the player constantly. This can't be due to my connection because speed tests report everything as fine and dandy.

Basically: I wanted to buy a song. It wasn't available. I ended up pirating it and donating money directly to the lead singer of the band.
Or in other words: windowing strategies cause others to make up for the deficiencies of the market reach. If you don't offer a free or paid option, someone is just going to infill it.
