In the nineties, Linux/OSS wasn't as mature/widespread and hardware for small devices sucked in performance and price. People wanted OSes and shit that just "worked". Installing and configuring "alternate" OSes in the '90s was painful even for experienced professionals and hobbyists. And the applications and user experience wasn't that great compared to what we have now.
Now days I can install Linux on a mainstream laptop, restrict Windows to a VM and actually get shit done without any or that much pain.
