it's an interesting idea. but it still has data caps, overage charges, locks you in a 2 year contract and sits on top of verizons' cdma. the company is also apparently a traditionally structured hierarchical autocratic corporation.
with regard to that, all the carriers have a benevolence wing (https://twitter.com/verizongiving for instance). So I guess cynically one can say this is just traditional capitalism with a different foot forward for a different demographic ... There's a very real ngo-industrial complex and they seem to highlight that that's where the money goes.
The SPLC for instance, has many members who make $100s of k a year in legal fees on behalf of the SPLC on top of their $300k salaries. They were also sitting on over $200 million of unused cash and made it an endowment that they invested in the market with ... these people involved in these charities have taken the donations of their members to propel themselves into the 1%. Splendid.
