speaking on behalf of the company i lead (which is in a comparable situation), we would love to invest more in the toolchain, but we are simply stretched too thin and are unable to make all the commitments we would like to.
ultimately "investment" has to come from somewhere, and it has been challenging post-QT to persuade people sitting on large piles of cash to make these sorts of collective-interest investments instead of parking it at the fed.
TLDR; too few personnel, too high interest rates
