Actually, the license does not let you share the item either. Your grandchild is not allowed to come to your house and play with it.
This license is a ridiculous piece of something, used by Bambu for them to be able to sue if they need to. A collateral damage of their choice is people who rightly can’t wrap their head around the fact that the license is indeed that ridiculous and are breaking it left and right. That’s it.
By the way, someone mentioned first sale doctrine. It does not apply here. You didn’t buy a book. You copied a copyrighted work, and you may only do that with permission of the author, and only under their conditions, which may include “burn after reading” if they like. (Fair use notwithstanding yadda yadda, all the above is about US laws).
