Coupla things..
The Ford Bronco was VERY MUCH inspired by the Scout. Not so much from a design standpoint but as a vehicle type in a market that was growing. Ford took note of how well podunk little IH was doing with the Scout and figured they needed to be in on that game. The compact SUV market was growing and the big thing that IH did was to prove that a more comfortable and more daily driver-friendly rig would sell. Ford already was working towards a new truck lineup, so some of the technology being developed for it translated well into the new compact SUV, soon to be called "Bronco."
IH's success with the Scout was as much an accident as anything. Their original concept was for a compact pickup. The full length top was really an afterthought but after people began ordering station wagons 8-1 over the pickups, IH switched gears and adapted more to cover the wagon market more than the compact pickup. Anyway, Ford took note, let IH do the market research for them and then jumped in like a fat man in a small pool.
As to your Bronco being called a Jeep, remember a few things:
1- There are "Jeeps" (in caps for the trademarked corporate name).
2- And there are "jeeps" (lower case, a general description for a compact 4x4 vehicle). If you pick up a dictionary, you will see a generic "compact 4x4" definition for the lower case word. And the word "jeep" predated the trademark by quite a long time. Years ago I did a story called "Will the Real Jeep Please Stand Up." In it, I outlined all the vehicles called Jeep before Willys-Overland trademarked the name in 1950. Story is online somewhere.
Also, what trademarked look epitomizes "Jeep?" The 7-slot grille, of course. Here is some ammo to use with Jeep guys: Ford invented that look. When Ford was contracted to build the standardized WWII jeep, one of their engineers noted that the welded slat grille was very labor-intensive to build so he developed a simple one-piece sheet metal stamping to replace it. Instead of a welder taking 25 minutes to zap together a grill, one "KERCHUNK" with a stamping machine and instant grille. This was the WWII 9-slot grille that became the iconic look. W-O adapted it for the civvy Jeeps, making it a 7-slot because they had to use larger headlights. So, the most iconic part of the Jeep "legendary" look was a Ford design. (this is an appropriate time to "Barney Fife.")
Finally, Ford designed and built their own contender in the process of developing a standardized military 1/4-ton 4x4 in 1940 for the buildup to WWII. In many ways, it was the best design and if you compare the individual prototypes from Ford, Willys and Bantam to the standardized design (a design the military largely directed), which one looks most like it? The Ford! Some of the other iconic items Jeeps are known for were developed by Ford: one of them is the T-handled hood hold-down.
Willys-Overland won the brass ring for the Jeep solely by turning in the lowest bid. All three of the prototypes had been tested and found suitable, making the builders of them eligible to bid. Had Ford won the bid (it actually did for a short time), the military would have required many of the same changes they did of W-O as they developed a standardized design... a design that had a LOT of Ford DNA in it. Willys got away with claiming to have "invented" the jeep simply because Ford didn't care enough to contest it and Bantam (the REAL inventor of the basic design) was too small and weak to fight it.
I don't want to take anything away from W-O, and it's corporate progeny, for developing a great product. Too often, however, Ford is left out of that great story.
So, now when you are looking at a Jeep and a sneer starts to come to your mouth, remember that there is a lot of Ford DNA in them. It's OK to remind Jeep owners of this!
