if cc gave a free sub with every PSP purchase it would hurt them more for the short run. CC i heard gets $30 a sub for each activation, taking that away from GZFX PMI.
I guess in an economic sense, it would depend on exactly how much profit CC retains for each sale of PCP. If it exceeds the $30 they receive from GZFX subscriptions, then yes, it would make monetary sense and would be win win.
