What kind of "full data" would you want from the customer? Earlier, you mentioned their name. Why can't the customer's transaction be as anonymous as possible, if they choose to be?
It seems as if Amazon, likely prodded by the GDPR and CCPA, is limiting the personal information they share with third parties. I think that's a good thing, for the consumer at least.
That's a slippery slope: is the person the seller customer, or Amazon's customer?
Their name was an example of something required to provide feedback, make amendments, or any kind of engagement that's required with that customer.
Anonymity is one of the reasons review manipulation thrives on Amazon.
Honestly I doubt it was due to GDPR/CCPA, or user privacy concerns, and more turning FBA into a pipeline of homogeneous suppliers that race to the bottom.
