Why would I do that? Flickr embeds still work fine after almost 20 years and did even when Yahoo owned it. They're now owned by a company that sells real, actual things in service to paying customers and has for a long time (older than Flickr), so I don't see any reason they would go the route most widget/embeds did and pile trackers in.
Incentives are the key. AdTech took over most things, but this is a rare oasis of that lost web.
My comment was neither specific to Flickr nor whether embeds technically work but on the issue of privacy, security and performance of a website especially since the notion of 'early web' was invoked.
