It's true, and often it's not laziness - corporate security measures are often focused only on denying access, and they're so overbearing that, were they followed to the letter, they could easily shut the company down. It's through workarounds that actual work gets done.
Sounds like a large organizational incentive intergration failure where subpieces are at odds such that they care more about dodging blame and outside of their domain it isn't their problem. "Not My Fault/Not My Problem" as a toxic approach making balancing decisions worse.
I remember having issues with a corporate email system where base64/uuencoded data would fail to get through with a very rough dependency on size - large files had a smaller chance of getting through but it was clear that there wasn't a hard size limit. Eventually someone twigged that the problem was a "rude word" scanner, and that beyond a certain size you would hit the "scunthorpe" problem, and forbidden words would appear in the ASCII text randomly.
