I'm not crazy about the idea of competing for charging stations with non Teslas. But if this allows Tesla to build Superchargers on less used routes where there wouldn't be enough business to support a regular Tesla Supercharger I'm all for it.
In our 4,100 Km long drive last spring we never had to wait to charge at any Supercharger. And we only found one charging station (at an 8 station Supercharger) out of order. And in every other case we simply plugged it and it charged. So the comment about the high reliability of Tesla Superchargers is accurate.
