I totally agree.
Who cares if the McDonald's ice cream machine is broken? It's shit ice cream. Most of you probably live near a better local ice cream/soft serve/custard joint. Heck, most of you probably live near a better corporate chain ice cream joint that probably also serves better food than McDonald's: Dairy Queen, In-N-Out, Shake Shack, Culver's, etc.
If McDonald's didn't have breakfast or coffee the whole chain might be out of business or at tiny fraction of its current size by now.
The McDonald's ice cream machine monopoly only negatively affects millionaire McDonald's franchise owners who deserve to be abused by the franchise for being so un-innovative that they resort to purchasing/renting access to a successful business model. Talk about the most opposite-of-meritocracy business venture imaginable!
Imagine if you had a half a million dollars in freely available non-borrowed assets and you couldn't think of your own business model to try. What does that say about you as an entrepreneur/trust fund kid?
Of course, ice cream is damn easy to make at home, can be made in large batches and kept frozen forever, and it'll come out far better than any fast food ice cream I know of.
