This is an incredibly tone-deaf and condescending response.  "Sometimes there's a learning curve to learning something new"?!?!!?? Really?!!?  Why on earth should an accounting program require its users to be required to learn a new, non-standard method of doing something?   Accounts should all be Debit Credit - full stop.  There are generally accepted accounting practices for a reason.   At the very least, if you want to keep that ridiculous increase / decrease labeling, offer a toggle that allows user to switch back and forth.
