Not the author of the OP, but we find nearly-identical numbers (slightly higher, in fact - see blog post in my submissions) in our data, which is self-reported by people signing up with us looking for jobs. When they enter remote-only, they're taking themselves out of contention for in-office jobs, so it's a fairly costly signal.
Okay, that's useful information. But then the number is 40% of engineerings seeking employment, not overall. It is also for those engineers using your platform, which will also be a biased sample.
