At least half of every enterprise software I have used suffers from catastrophic link rot. And when you look at the URLs that do still map or redirect to something marginally on-topic, you just know it's a single API change away from redirecting to "we don't know what you're looking for, try searching here for hundreds of completely off topic (and occasionally broken) links".

No, I am not bitter. Learning where their FTP server is and how to navigate, well, that was gold.
