It's more like #linux users know how to use the #internet, they just use #duckduckgo to search for easy problems and don't ask for every little thing.
And they are mostly more advanced users, who know what an #application is and how to open one, therefore easy questions don't get asked.
But the main point is very true. You don't need to know that to use Linux. I started Linux when I didn't know what #apt or even the #terminal was.
