One of last form of lock-in that I'm struggling with is iCloud Photo Library. A service that has been a blessing and a curse. I've been saving my photos there for the better part of a decade.
I'm working on getting my photos out (first by requesting my data from Apple, then from iCloud Drive on Windows) and I'm appalled - everything gets dumped into one directory. Inconsistent file naming. Timestamps not always accurate, and "Date Taken" seems to have disappeared from a number of my photos. Albums are not included (unless you count them being a list dumped into a csv). All of that data is kept inside iCloud.. only for them- not for you.
So what comes next is a long journey to re-organize all of my photos by year, month. I'm not even sure if my Hidden photos got copied over.
This is all 100% a dark pattern to keep users locked into Apple. How many people would get this far? Not many- my wife would have given up at having to request her data from Apple. Then how many would stop when they find out all of your photos get dumped into a single directory (30k photos!) if you try to leave?
All of this is to say, I'm done with Apple. I want control of my data, not this circus show.
