Private vs public space on FamilySearch Family Tree

FamilySearch are encouraging people to add more items to a person via the Memories app or feature. This is to let others get to know the person better. We can add photos, documents, stories and even audio recordings or files.
Who can see all this stuff?
If you are adding it on the memories tab of a deceased ancestor, then this information is visible by anyone who visits that persons tree. Deceased people are part of the one global Family tree and hence  their information is public.
If you are adding it to your personal or private space of yourself or another living relative then this information is private and won’t appear in searches unless you tag a deceased relative in your memory item.
Once you pass on are are marked as deceased, all your memories become publicly viewable.

Edit Rights: Only the patron first submitting the memory has edit or deletion rights. Once that patron is deceased, the edit rights die with them. i.e. nobody in the future can edit or delete the memory from that patron's memory space.
