That’s my understanding - a lot of the low power devices were big endian as for whatever reason big endian and risc seemed heavily correlated for decades, similarly the early mainframes and whatnot were big endian which is why a lot of network protocols use big endian formats.

I've noticed that decisions like this are sometimes made for the sake of being the opposite of something else and then the two coexist decades within neighboring realms to the frustration and bafflement of users.
