If I tell you to buy 'Y' from Amazon using my account, I have given authorization for that purchase even though it is not me, the owner of the account, making the purchase.
In a similar fashion, Perplexity can claim the user telling their software to make the purchase is no different. That it is not a human is irrelevant. The owner of the account has given permission to make the purchases.
