Incorrect - The expectation of an executable file like Windows forces users to get off the internet is precisely one of the things Linux FIXED - It is a point of education, as it's a massive security breach, but the status-quo of software downloading on windows made such actions normalised.

How does Linux fix this? Repo-based package-management using a GUI AppStore a la KDE Discover and Gnome Software. It's how grandmas download facebook on their phones, and it's exactly Linux's strength, it just needs a push on that front.
