We don't mess with them. All of the things that Stacy Jean noted in her answer to the question (Stacy Jean's answer ), we noticed years and years ago.

Don't assume that everything that shows up in a hotel is a 'profit center' simply because it comes at a price. Sometimes, it's simply there for guest convenience. (Indeed, many people miss many of the things that, over the years, have been eliminated because it neither can be provided at a good enough profit for the hotel to be much of a 'profit center', nor can the hotel give it out as a free amenity; and in either case, can be provided at the cost of more bother than it's worth. See Michael Forrest Jones' answer to What features of restaurants and hotels have almost completely vanished? .)
Long-distance telephone is one modern-day example: the 'profit' from it is negligible, unless you price it so high that the guest feels like she's been gouged when the call shows up on her bill. Indeed, even Red Roof Inns offer it as a free amenity. (And Red Roof is an economy chain: one of the things that go with successfully running an economy property is aggressively watching the bottom line - and watching it with the free amenities, especially those that you can't limit a guest's use of.)
