Earlier quoted context omitted.
I bought an iPhone a couple of days ago, and was planning on using the weekend to finally migrate from my old Android phone. Luckily, I haven't even opened the box so I should be able to return it for a full refund. No way I'm spending over $1000 for this kind of experience.
Google has done the exact same thing in the past, deleting Google accounts without warning (which is arguably worse because not only can you not access your phone backups but your email, calendar, drive, etc. is gone too).
Some people use iCloud for email, calendar and storage so for them I imagine losing access to Apple ID would be just as bad.
