For reference, that's buying: Amazon Prime ($10), two channels on Prime ($20), Netflix and another streaming ($20), and a streaming TV subscription ($40-50). Notably missing is Disney SVOD -- though some Disney content is carried by the streaming TV.
Given the frustration of having to use multiple apps and services while still not getting everything because of the massive fragmentation -- never mind that most people can't afford anywhere near that a month on TV -- I'm not surprised people are pirating content.
