In many cases, choosing libraries and frameworks is motivated by political/symbolical reasons, and might not even expected to have any technical benefits.

At one point choosing java enterprise was about signalling ambition and competence. Nowadays service architectures/cloud etc serve this role of "decorative" tech choices. These types of choices factor out responsibility (of end results) from individuals while expanding their "organizational footprints" and giving their CVs a fashion make-over. Those are the incentives.

There would need to be counter-incentives.
