Reminds me of my sister's Ford F150 oil pan leak issue. The oil pan is plastic (for weight control, certainly not durability). After a while they leak. There are thousands of F150s with leaking oil pans and there are no aftermarket oil pans that one can buy to replace the OEM pan.
Her truck is on its 3rd or 4th oil pan. They must replace the pan when it develops a leak. It isn't as simple as replacing a gasket or squeezing some sealant on the old pan and torquing the bolts. You must replace the pan. This means logistically that you are trapped in a supply chain problem when you buy the vehicle since the new pans need to exist before you can use them to replace a leaky pan. When you take your truck to the dealership they may have it for weeks waiting on parts.
Once they get the pan you can relax since it will be installed by trained Ford techs with approved Ford parts. Well not really. Turns out that Ford's bulletin goes into detail about the procedure and in the end reminds the tech that any deviation from their bulletin procedure will result in a leak which will require replacement of the replacement pan since it is now an unreliable, used part.
Vehicle cost a lot of money. Hers has been out of service for this single issue several times for a total of more than a month of lost time.
Somehow I am supposed to trust that a company that produces a vehicle with a plastic oil pan which is not a part that anyone familiar with automobiles would ever consider to be a wear part, can reliably produce a digital display that can remain in service, working perfectly for at least a decade and that once it fails it can easily and cheaply be replaced by the owner if the owner chooses to keep the vehicle.
This is not rocket science people. While scanning wrecking yards looking for parts for a couple of my older, but still well-maintained vehicles, I have found cars and trucks in great condition that are in the wrecking yard because the owner thought they couldn't afford the repair. For one of my vehicles the repair part that the junk donor needed was widely available at any auto parts store for under $100 and could be installed by anyone who had a phillips screwdriver and a metric socket set that included a 10mm socket.
I can't imagine that a digital gauge display will be user-replaceable or inexpensive.
Ford doesn't make displays. The people making the displays are vastly different people from the people making the oil pan. This is a pretty key part you're ignoring here.
As far as the oil pan, the design of the pan probably makes it too complex to manufacture at scale in a material that is more durable. It is not a simple cake-pan style reservoir. It has mating surfaces and ports that would be difficult to reproduce in metal. Here is the TSB that Ford techs need to follow to accomplish this temporary repair.[0]

Here you're absolutely equating their failure at making a reliable oil pan as a reason to question them producing a digital display. Ford isn't producing the display. Their failure to make a reliable oil pan is pretty disconnected to them buying screens from an automotive supplier.
Ford isn't producing any displays, so questioning their ability to source a display given their failure at making a good oil pan on one generation of one vehicle is pretty moot.
As a counter point to displays being unreliable that, I've had Ford vehicles with displays that have lasted well over a decade so far, and to my knowledge still work. I've never had an automotive part have the display just fail on its own, personally.
As for them deciding to stop supplying them, eventually they'll also stop supplying the "analog" gauges as well, so its once again a moot point. That "analog" display can still fail requiring replacement. You're not avoiding that problem having needles instead of an LCD.
