This is why we added http cache headers, CDNs and caching of common assets, and cross domain requests. All of which are being assaulted for various levels of "privacy" concerns. Privacy I never asked for mind you, but I get it anyways. Though how convenient that tracking still happens, I still get ads, my content still doesn't belong to me, sites are slower, everything is an App, and the general experience and openness of the web is Down.
I exaggerate a bit to prove a point but the gist is definitely happening, we're just waking up to it slowly.
