Earlier quoted context omitted.
Or not? I remember when banks required you to have IE long after nobody was using IE. I remember when banks showed an alert against using Safari long after it became the most common mobile browser. Banks also have their own apps and are not dependent on Chrome.
That was in a time when expectations were low and all the banks were pretty equally crap. There are better choices now, and even my mum would be pissed off of her bank website didn’t work in her current browser.
People can change browser more easily than changing banks. They can even have multiple different browsers on their machine, and one for only doing banking.
