Windows power users expect their habits and instincts to be right and treat the system as broken wherever they aren't. After all, they "know computers"! So when one of them hits a snag, even if it would have been avoided by heeding a system's warnings, reading the documentation, or adhering to its norms, they declare (for others to repeat) things like "Linux isn't (ready) for power users".

They are used to mindlessly batting away constant notifications and distractions. They are also used to a host of familiar warnings that they know are bullshit, and reflexively ignore. But the warnings on Linux systems are not the warnings they know. They don't actually know what they mean or which are safe. To the point that their blindness to warnings becomes outright comical, as in this infamous example: https://i.imgur.com/J39WfLK.png
