Nor should it be. The day this becomes massively enforced (god forbid) is the day that an adblock-esque plugin will be created to bypass all of this idiotic government mandated nonsense. Those options exist in web browsers already.
And it is nonsense. It does nothing to protect users, for one. The average user has no idea what a cookie is, and will either blindly click accept or move on.
For two, its the government getting their hooks into mandating specific content on the web. Yes yes, slippery slope is a logical fallacy and all that, but when it comes to government expansion of power, it tends to ring true.
For three, it's a pain in the ass. I really do not care what kind of cookies random sites are sending me. If I did care, I'd be running a plugin to deal with it or changing my browser settings accordingly.
Fourth, it's more work for web developers for questionable benefit.
Maybe this is just me being a typical ignorant American, but this kind of nannyism is downright offensive to me.
