I had to log back into an account for an app (I think Taco Bell) that decided to remove passwords entirely without any notice. You typed in your email address, had to open your email account and click a link they sent you, it would open a webpage, which would then have a button to open the app again. If I remember correctly too, it would only work on Chrome, so I had to copy and paste the link since Chrome isn’t my default browser that automatically opens from my mobile email.

Besides that, I remember some website required a special character from an extremely small list and wouldn’t allow two of the same letter back-to-back.

if so wouldn’t that just end up with the USA following strange semantics other countries don’t?

When it comes to renaming external locations like this that are used by multiple countries, I would imagine it would be a case of how wide the rename is adopted. If I had to take a guess, renaming the Gulf of Mexico or the Atlantic Ocean in more US-centric names isn’t as likely to catch on globally and will probably just result in confusion when people from different countries are referring to the same thing.
