There are lots of ways to style these native controls, though, including ways to start from scratch and retain the accessibility affordances.

I'd be curious to know more about the usability issues you've found on mobile -- I've not had any personally when using radio buttons. I'll readily grant you that 'select' is awful everywhere though!

It’s a lot easier now than it used to be. Radio buttons used to be nearly impossible to style, and I still think they require scripting to de-select— so none in a group are selected after one has been selected. I’ll bet most of the complexity in the article is some combination of keeping support for older browsers, technical debt, and nobody complaining about it because it works.
