Tesla making superchargers available as well to cars made by other manufacturers could become an interesting development, at least during the early days. Having read during the past months/years that Tesla's chargers are very reliable (not buggy nor just "offline" for some weird reason - e.g. just this afternoon I wanted to charge my hybrid at a specific parking garage in Zurich/Switzerland but the whole floor where the chargers are located was closed), a lot of car owners might want to use them => Tesla owners might get angry seeing that "their" chargers are all busy by non-Tesla cars => advantage of owning a Tesla would suffer. On the other hand Tesla might get more (stable) earnings through this and the company might play with the charging cost, e.g. increasing the charging/parking cost for non-Tesla owners or at least taking more into consideration involving the cost the charging rate of the non-Tesla-car being charged and/or the time during which the charging station was busy. I guess that the worst/most-expensive combination would be "non-tesla" + "big empty battery" + "low charging throughput"?
