Agreed. And iMessage actually has the sender client generate the link preview and bundles that with the message. This sounds weird, but with end-to-end encrypted conversations, it's basically that or have it generated by the recipient. (or have one of the receiving client send it to a service out-of-band, but that "defeats" the end-to-end encryption.)

Having the sender do it also makes sense from an auth point of view— thinking of like a private Github repo, or something like Jira running on your corporate VPN. Presumably the sender intended to share the contents with every recipient anyway and any that don't have access still of course won't be able to click through. But it would be pretty bad UX if the card was just blank in these cases because the messaging server didn't have access.
