Everyone that complained about the wintel dominance I always found humorous because their alternative was PowerPC which was developed by Apple IBM and Motorola and fabbed by IBM. Not saying it was or wasn’t better, it just didn’t feel like a better alternative on the surface with it being done up by IBM and Apple.
There were so many architectures and they’ve all fallen off the face of the earth. My favorite search engine when I was a kid ran on 2 DEC alpha servers.
