Yes it is silly. The article actually ends with some useful tips: As a user, you can force allow zooming: In Firefox find the settings, select “Accessibility” and activate “Zoom on all website” In Chrome find the settings, select “Accessibility” and check “Force enable zoom”
I kind of wish the author had lead with this instead of burying it at the bottom. For whatever reach the article gets, this is the part that's going to offer value to readers (it seems unlikely this article will sway a significant number of web developers to change their habits).
Anyone can find the secret override setting if they're motivated, but that's not a solution to the problem.
I know web developers don't care, but they're still the ones that can actually solve the problem. It's possible that like many other abused web features, Google will eventually change the setting for this feature from "override website zoom settings" to "respect website preferences for zooming" with "off" as a default.
