FWIW, as far as I'm aware, it wasn't gmail scraping that was the cause of Amazon pulling that information. It was third-party plugins that read people's inboxes to provide them with coupons, discounts, etc., and those companies would sometimes sell the pricing data. I assume Amazon wasn't thrilled about that, but there wasn't anything they (or gmail) could do about it as long as the user was granting them access to their inbox.

But also - I just ordered something off of amazon and I noticed that the confirmation had the item that I ordered in it, albeit in a shortened/summarized way? So maybe they brought it back, figuring that with just part of the name, there's not much someone can do with the pricing information? Or maybe they just don't care anymore?

(disclosure: I work at google, but not on this, but worked adjacent to the gmail team for a few years and am going off of my memory. I'll also tap the sign that Google doesn't mine your gmail for ads, for both consumer AND paying customers).

Shopify in particular launched an app with the option of scraping your inbox.
