We let people create a username/password but can also use FB if they prefer. Turns out having their email is nice; we need to send them notices and reminders from time-to-time.

I’m not a FB fan. I post on social media maybe twice a year. As an advertiser I don’t trust the numbers they report. None of my criticisms of Apple in this decision should be interpreted as pro-FB. I just have a very strong distaste for Apple deciding that they get to decide how we run our apps.

They have to mandate usage because it’s the only way devs will do it. And it seems like a fine enough product for Apple-only hardware. But when you get to supporting multiple connected devices it falls apart. Are they going to support this for PCs? What about on the Roku? How will anyone who uses Apple Sign In on the iPhone log in anywhere else?
