There are non-Tesla DC superchargers in the US, but yes, the network of those chargers is much less reliable and less well planned in the US. (Versus Europe which maps show a much more thorough ChaDeMo network than the US, which is arguably accountable solely to relative population densities of the continents and Tesla's US-first market focus.)
ChaDeMo could still catch up with the right gumption (the rest of the auto manufacturers teaming up, for instance), and there's still a lot of talk about how the two "standards" are easily interoperable with simple adapters (and Tesla has a Tesla-to-ChaDeMo adapter, but so far as I'm aware no one has yet to negotiate for a ChaDeMo-to-Tesla adapter to be sold; Tesla is in a position of strength for now so hard to blame Tesla on hedging that position a bit in the US).
At least it looks like the different "winners" in the US versus Europe might keep the game competitive in the current term.
