I see it as: they're all trying really hard problems that aren't in the training data, to gauge if their models are improving, achieved by looking at problem that humans haven't been able to solve yet. The evidence to this is all the problems being publicized in the last few weeks.

If it was insecure and they found it first, that'd be better than many alternative actors who would eventually find the same exploit.

As are all companies working in quantum computing.
