In this day and age of convoluted terms of services (TOS/TOC), xyz as a service/subscription, and just plain DRM, no one really owns anything anymore. No one can be sure what version they do have is the original and immutable version. Edits and omissions happen because of licensing issues and just plan social activism. Problematic content should be acknowledged but not purged and erased.
It’s vital people have the means to share data regardless of what the powers that be allow to be shared.
