Stupid question, but given that most analytics are gathered via JS, I wonder if that might fall into the same sampling bias as "we called 100 random people and everyone has a phone!"

It's a good point. I'm not sure how it would be tracked. I just can't think of anyone I know that even might browse with JS off. It's on as a default setting and I think it is fair to say that most of the world don't know what JS is.

Hi new internet friend.

I have it whitelisted for some (perhaps many) sites. But even if it was on, things like google analytics are still blocked (at least I hope they are! Tracking is a never-ending battle)

Most people leave JS on, but several browsers (e.g., Tor browser) and browser extensions make it easy to turn ir off (e.g. for improved security). Many tools, e.g. Lynx, curl, wget, do not implement JavaScript.

In the last 20 years doing web development, I haven't ever had one single colleague, friend or customer complaining of any site not working because they had disabled JavaScript. Literally didn't heard about anyone around me with this problem not even a single time.

The only place I randomly see mentions this problem is in HN.

That has to count for something.

Some of it, too, is that if it were more practical, more people would disable it.
