I read HN every day and love the discourse on the advanced, mature, wide-ranging and ever-evolving toolsets for modern front-end development.

Because I often see things like this, today (and every day recently) when I log into my cell phone provider's web site (Vodafone), and am greeted with this large, prominent widget first thing at the top of the page:

How is stuff like this still so common in modern web development?
