Completely agree. I just used the work around that was posted in 2020 (attached), but I had to remove my last older childre in order to add my original itunes account to the family share (which has my personal email that I had before getting my icloud.com email). That's another issue I have had with Apple - I have 7 kids and when my younger ones got ipads, I had to kick off the older kids (HS & college age) so that I could manage the ipads. I wrote a letter to Apple and also talked with tech support about the 6 person family limit. I even went so far as to suggest that I would be OK with using some method to verify that i indeed had 7 children and was not trying to share my purchases with friends.
Anyway - just recently hit the 2TB limit with our current devices (3 iphones, 5 ipads, 1 iMac, 3 macbooks) and I alone have over 1TB of photos/videos in my icloud account. Getting to the 4TB is a pain in the ass since I can't combine my icloud with my itunes account. Still not sure if this is gonna work.
