So many disagrees here, but apparently Tesla agrees with me that the Supercharger price increases are risky. Smart move Tesla
Risky? What does risk have to do with it? Do you really think people will not buy a Tesla because the price of supercharging has gone up by a few cents per kWh?
At least Tesla has a supercharging network, which cannot be said of Jaguar, Audi and Porsche and the other 'competitors' you adore (even though they need it a lot more with their poor efficiency).
Paying a few cents more per kWh for the 5% of the time that people use a supercharger (the rest of the time they charge at home) will not make a difference. Just like the end of free supercharging for Model S and X did not make a difference.
