"Enables a new option to upload credit cards to Google Payments for sync to all Chrome devices. – Mac, Windows, Linux, Chrome OS, Android, Fuchsia"
They've really ramped up the "Google" in Google Chrome these last few years. The "save payment" nag box was annoying before, now I'd move it firmly into the dark pattern region, as it attempts to convince you to move your payment into their payment services not just saved locally.
The fact that there is no "never ask me again" option for that save payment dialog seems like nefarious UI 101. How could a billion dollar company make such a rudimentary UI mistake in a flagship product? Well, they probably didn't make a mistake, they're just getting worse as a company.
Meanwhile, I am blocked from reading any more of that twitter thread by the uncloseable twitter sign up nag screen. What an antagonistic web!
