I have JavaScript disabled on my phone.
Without technical measures, the web is just painful. Sites take long to load, they jump around, obscure the viewport with all kinds of sticky content, show maliciously compliant cookie screens, interrupt reading with delayed newsletter popups - there's just no end to it.
On the desktop there are extensions to get an acceptable experience but not on iOS. Disabling JS may be radical but it yields a butter smooth, battery efficient, mostly crap-free experience. For problematic sites there's the back button or a back up browser with JS enabled.
