A major problem with blocking third party cookies is that it kills any embeddable logged in experience. Think payment gateway widgets that would now require you to login every time you want to make a purchase, or youtube embeds that would no longer recognize your premium subscription and roll ads across the web if if you pay for none, etc.

And that's the only good use case for third-party cookies. I'm willing to sacrifice that if it would mean that reliable cross-site tracking is made impossible.

That's what browsers are working on Federated Credential Management APIs for: https://developer.mozilla.org/docs/Web/API/FedCM_API

It would have been nice to have a replacement for it ready and shipped before they started getting removed.

They haven't gotten removed yet, just compartmentalised and some important existing ones grandfathered in, I believe. And none of that has happened in Chrome, as far as I know.

I wonder if the first part of the statement is true actually. What if the laws of interaction between space, energy and matter were poured in along with the space, energy and matter itself?

I suppose that amounts to the same thing as what I’m saying.

amazing tool. if you have any tools in the shop with radio-remote (like lights, or a vacuum) - this tool can make you an evil king of a haunted space. but don't do that tho.
