Some companies love to blame vendors for their own non-payment. The blameshift works when users only have the company's (the actual customer's) word for it.

Having basic transparency like "this service is in read-only due to nonpayment" really helps internal users to realize the company is being a bad customer. Which then pushes the company's reps to actually pay for the service.

So, no it's not inexcusable.
