I do a lot of responsive design, and I turn zooming off So I CAN give you a proper responsive design that you can read and interact with on a small touchscreen. Why on earth would you prefer to pan around a desktop site designed for a big screen with a tiny cursor when you've got a tiny screen and a massive cursor (fingertip)?
Consider your post score an informal poll....
Have I been on sites where I wished zoom was DISabled? Yes
The point is, I design my stuff so it feels like a native app. I design my stuff so it is as accessible as the apps that came with the device. Zooming is a feature added to mobile browsers so mobile users have a fallback to view websites that dont support mobile screen sizes, but designing websites for mobile intentionally to make use of a fallback for non-mobile support isn't using the mobile device to its fullest potential?
Without zooming, how do you all use things on your phones that ARENT websites? They don't zoom either...
If I enable zooming for users, every tap on every mobile device is going to get slower for every user. Is that in the interest of better UI?
Do you think users tap more, or zoom more when using web apps?
Would you rather fill out a desktop Credit Card subscription form by zooming and panning around, or using a form designed to be input with a thumb where all of the fields are fit to the screen width?
I can tell you right now, if I designed our sites like some of these HN commenters want it would be comfy for them to browse and we would lose thousands of dollars revenue. As others have noticed, there are browsers that have a zoom override, as well as bookmarklets and other ways you can bypass the no-zoom thing if you're a mobile user with special needs or who likes zooming. YOU can enabled that device-wide for yourself if that's how you like it, but it doesn't make sense for all projects to be built the same way when the goals and intended support for projects varies widely.
