Geez, I skimmed the image with the "steps" and the devtools next to it and assumed it was steps to get the user to open the DevTools, but later when he said it would download a file I thought "You can tell the DevTools to download a file and execute it as a shell script?!". Then I read the steps again, step 2 is "Type in 'Terminal'"... oh come on, will many people fall for that?
Also, I’d bet the average site owner does not know what a terminal is. Think small business owners. Plus the thought of losing revenue because their site is unusable injects a level of urgency which means they’re less likely to stop and think about what they’re doing.
