Inertia and other standards are a big force here.
The NIST standards recommending this (SP 800-63B I believe, under "memorized secrets") came out in around 2017, many years after large companies had settled on prior standards. Prior standards were closer to what banks / other biggies were doing and they just kept on doing it. In addition you may have other non US govt policies (UK for example likes to publish policy docs, see: https://www.ncsc.gov.uk/collection/passwords/updating-your-a... for their slightly different modern take) which the company prefers to use because of either their own HQ location or large customer pull.
Better yet many different countries requirements and a couple industry docs are cobbled together into a frankenstein set of requirements. That requirements docs is then treated as though it came from Mount Sinai and should not be altered without getting the approval of 3 senior VPs, a professor of cryptography, and the head of IT.
