Calling this fusion ignition is stupid. Laser fusion is unlike other fusion devices in that the efficiency of laser is extremely low. It is true that the reaction created 3MJ when the laser energy input INTO THE REACTION CHAMBER is 2MJ. But the whole laser system took 300MJ to run for this one shot. Thus the real Q value is extremely low compared to other fusion methods.

Note that the announcements refer to laser energy supplied to the target, not laser energy entering the chamber. The former is a fraction of the latter, and the basis for the term “scientific gain”. The actual target gain may be < 1.
I'm not sure I understand your criticism
