Both groups will operate on a wide spectrum, but if we're already generalizing...

Perhaps there's a matter of competing priorities?

Programmers are usually quite cynical overall, but in this case I see it as a "My CEO is telling me _out loud_ that they want to replace me, so why would I help them speed up that process?"

Investors likely want what they're invested in to appreciate, so I imagine they're likely over-leveraged and are doing what they can to get their bag.
