Because if it is quantum it's a generation 0 (barely out of prototype) implementation going up against a generation... oh I don't know... 30+ classical computer. If it's not quantum, if it's basically an ASIC chip designed to solve simulated annealing problems (intentionally or not), it's worthless even as research. What they are selling is a research and training system, so that engineers can learn what kinds of problems can be solved on the hardware that will, presumably, get much more powerful going forward.
Look at it this way, the current D-wave machine has 512 qbits and a modern PC can match it's speed. Double the qbits and you end up with a simulation space several million times larger, the 15x faster is going to seem laughable when the problem you are solving is trillions of times larger and the D-Wave solves in constant time while your PC runs an algorithm that's O(n^2). If, if, what D-wave is selling is using quantum affects.
