Same with Ford. And while I do think the addresses should be returned, they should get market value or above for them. We should not punish companies for buying into the future, which turned out to be a great investment.
Alternative view - those addresses should not be "returned". They're owned. I hope hoarders will get blocks as large as they can so that we experience real shortage and start seeing the first ipv6-only services.
They probably got a /8 early and gave each regional office their own /16, so they'd have to unpick all the addresses they're currently using before they could sell off any.
Gonna be funny how well likely live to see ipv6 run out of ip space leading to ipv8!
