For myself a quick fact check like this is also low effort. Unlike the author, I recognize this is a professional skill. We are fortunate enough to be incredibly proficient in a large set of skills. Language, literacy, reading quickly, tech skills, research, touch-typing, critical thinking, searching, subject matter expertise, etc. Most people don’t have those skills! For them to do the same fact check it would be an enormous effort, if they could even accomplish it at all. If these skills were common, our society would not be where it is right now.
Imagine a very tall professional basketball player casually performing a slam dunk. Then they tell you it’s super easy and berate you for not being able to dunk.
Us terminally online people who spend all day reading, searching, and writing are mostly interacting with other similar people. I’ve been doing that almost daily for over twenty years. It’s a skill, and it is an incredibly rare skill. This is easy to forget when you mostly interact online only with other people who have a similar level of proficiency.
