Aren't those requests made from client devices?
They are for anything that's E2E encrypted such as Messenger and WhatsApp, so that the link isn't revealed to Meta servers.
As far as I know, for things like posts on Facebook, the server does the scraping. This is especially the case in the web version, since client-side scraping of arbitrary sites would require those sites to have an open CORS policy, which comes with security risks.
There's a Sharing Debugger tool on the Facebook developer site that lets you force rescrape a site.
