I don't believe you.
Here's one example:
> > focus should never move without the user doing it", On iOS using Chrome: you visit a webpage. That page has an ad for an app. The app-store opens, which steals focus from Chrome. This is on a "modern" browser and OS.
Most of his rant is accurate and is not related to old browsers or old OSs but to the fucking stupid things that many web designers do.
I'm one of the whatever percent of people that is mostly satisfied with my browser. It stays almost entirely out of my way. My UX issues on the web are typically due to the web.
So to answer your question, some people may be making that choice, but I, like most people, am not.
And it's something that many people have noticed and commented on. See ancient discussions about the version of Nero / ACDSEE / whatever that don't suck.
It is unbelievably stupid to stay on such an old browser. Browsers are the main vector of attacking an individual user, and you can't sacrifice security updates in order to keep a UI that you seem to prefer.
