This is not an import, it's a sweep of a wallet, with a transaction on the blockchain and fees paid. Jaxx (and you) should avoid using unsuitable terms. It confuses beginners and let them be scammed more easily.
Beginners should be taught the right terms for the right features since their very first steps IMO.
I have absolutely no idea what part of the quote you're referring to.
Did you even read anything before you expressed your criticism?
Here the full amount of the paper wallet is sweeped automatically during import.
Some wallets only import the private key, so there is no transaction taking place and you would have access via both wallets.
After sweeping the paper wallet with the respective wallet application (in my case Jaxx) it is empty anyway.
and even in the tutorial I noted:
Info: A transaction is executed here. The Paper Wallet is now empty! The Bitcoin are now exclusively in/accessed through the Jaxx Wallet!
So I can't really figure out where the problem is for you here.
