It makes the most sense for a company to spread their risk amongst as many suppliers as possible if their entire business relies on the performance of those suppliers.
Thinking about it, IT hardware and networking doesn’t ever seem to do this. Maybe that’s because it’s lots of items working together to create a system instead of multiple discrete systems.
It also makes sense for a company to reduce the number of different makes and models of aircraft so that a pilot can move from one to another without too much retraining, so they can reduce the size of spare parts inventories, service more aircraft at fewer locations, stuff like that.
A guess but maybe the reason it looks like it’s mostly boeing is because enough people have started using the services that allow you to search based on plane type that non-boeing planes are filling up which means most space available is on boeing planes.
Unsubstantiated guess, but based on a cursory search for flights on Delta, it seems like 90% are Boeing.
2 years old, but should be somewhat indicative. A lot of em seem to be 50/50 Airbus/Boeing (except Southwest, yikes), but anecdotally I’ve flown 4 times and it’s always been a Boeing.

And using different vendors is absolutely a thing in IT systems: https://www.telcion.com/blog/security-vendors-is-it-better-to-have-one-or-multiple
