We have a service running on a Linux VM, using open-source software. It works. Got a request from the marketing department to migrate the service to a paid hosted version that they used at a previous job. OK. No problem. After you create the account with the paid service you’re going to want to add my team as admin users so we can support it. You’re also going to want to add the accounting department as billing users so they can set up the payment portion, otherwise you’re going to have to submit an expense every month.

Their response? “We’ll just keep using the one you built us.”

Quite deliberate.

And here is the origin of the term, by Dilbert.
