Though even if we decentralize DNS, ICANN controls all of the underlying IP addresses.

IANA would have to un-delegate a whole range from RIPE.

I don't see that happening unless they want to fracture the network.

Perhaps Elsevier will be able to force ISPs to blacklist that particular IP, but nothing more.

I also suspect they will move the domain under a ccTLD, not subject to the whims of ICANN.

check out namecoin. they are attempting that, afaik.
