>but a bunch of the internet breaks if you do that.

not really, no. From my experience most stuff works fine (the thing that breaks websites the most is webgl and even then, only the few websites that really need it use it)

You would be surprised at what breaks. It also prevents local storage (not just cookies) from working at all when inside an iframe. That took me a long time at work to debug.

More importantly, instead of silently failing like localStorage should, the attribute on the window object is missing, causing page scripts that don't catch the exception (ie all of them) to crash and usually break the page.

I'm pretty sure Google is making disabling cookies as painful and breakage-inducing as possible to make sure people don't flip the switch.
