They are doing research, they've sold a couple to various organizations, even Google bought one.
While traditional computation might not be price-performance compatible if the D-Wave is a true quantum computer (which was doubted for a while, and maybe still is) then a) You can do stuff on it that you will be able to do only on quantum computers and b) (prob the most important part, and hardest part to get right besides building the damn thing) is that you gain experience in translating traditional computational algorithms into quantum computing algorithms which is very very important for the field to take off.
For Google, Microsoft and other big companies that's a very important thing to achieve in order to secure their future once quantum computing becomes a reality.
