Warner claims this kind of taxing scheme would generate "$20 billion annually". Of course, at the expense of the consumer, many of whom may want nothing to do with getting music for free or even getting it online at all. Considering that many ISPs compete fiercely on pricing, with many broadband connections starting at under $30, putting what is in relative terms a monumental tax onto a monthly bill solely for music is just ridiculous.
A "music industry veteran", Jim Griffin, believes that ISPs will embrace the plan, and cites support from certain industry players, including the EFF. However, the EFF's stance was an opt-in approach that was voluntary, not a forced tax. Somehow I don't see ISPs embracing a forced tax anytime soon.
