> Do you expect Amazon marketplace sellers to be able to link to their items being on ebay or shopify from the actual Amazon website?
From the Amazon website? No. From the products they're selling? Yes, absolutely, and lots of them do, I get one of those business cards with "Find us on Amazon/Ebay/Shopify/whatever" in the box with almost every purchase.
Same with apps. I obviously don't expect them to link to items from other stores from their App Store description pages. But from their application? Yes, I totally expect that.
That's how marketplaces everywhere work, including IRL. Go to any farmer's market and most sellers will give you a business card with their website or phone number so you can also order from them directly, or from their Amazon/Shopify/whatever page.
Edit: not to mention that this is 2025, the distinction between "within the app" and "via your website" is pretty meaningless in a bunch of cases.
