Can someone explain the backstory behind this? I'm reading some of the comments here and I feel like I'm missing something here.
They were planning to change it to a custom domain, which would allow sites to easily filter out and reject "Hide my email" users based on the email.
They have now reverted their plans to change this, meaning "hide my email" is still "@icloud.com".
Whereas people's Apple emails are often at @icloud.com
So I don't think it masks you amongst all iCloud users. I'm confused how this is much better!
These are two separate services. The problem was with the latter not the former. If the service decides to block @private.icloud.com they might as well remove Apple's sign in button.
