Look, I like Linux too, and I think governments should definitely use it to move away from Microsoft.
But as long as prebuilt PCs and laptops are sold with Windows, people will stay accustomed to it and be way more hesitant to switch.
You can tell them, 'It works just like Windows! It just looks a bit different!' Yet their minds will still think, 'New = scary.' and won't use it.
The issue for me as a potential advocate to my immediate circle of friends and family is that I don't want to become the only source of tech support. Now realistically they'll probably have fewer issues, but as soon as they want to fix something they'll have to come to me. No they won't Google things, and if they do they won't understand it.
That was true in the past. But in the last 10 years people have stalled their PC upgrades. That's the real reason why they don't move to Win11, because they don't want to buy a new PC. And that's where Linux is going to get that market from MS.
