Shifting goalposts. D-Wave's critics indeed spent years claiming that the machines were hoaxes and offered no quantum effects. Understandable, as extraordinary claims require extraordinary evidence and D-Wave was found wanting for some time. Other critics claimed the entire field of quantum computing was fraudulent--this was a hobby horse of cranks and conspiracy theorists, but unfortunately CS attracts a fair number of those. Google's validation of D-Wave's current technology shuts down both those camps of critics.
