In the workplace, there are still a lot of domain specific programs that don't have Linux support. Companies don't have much of an incentive to port that stuff over. As for the people who just need a web browser, they probably would use Linux just fine if they could buy a computer at BestBuy that comes with Linux preinstalled

Compare that to LLM programs, where it's a matter of "download this app instead of that one, because this one is free and that one costs $25 a month"
