His Royal Highness Prince Michael of Sealand said in an interview with 'CBC The Hour' (->Youtube) that buying Sealand is probably a good way to circumvent international copyright law, but that he won't sell sealand to the Pirate Bay. Here's a bit:

Prince Michael, also known as Michael Bates, said the following about the activities of the popular BitTorrent tracker. “It's theft of proprietary rights, it doesn't suit us at all. In fact, I've written a book and Hollywood is making a movie out of it, so it would go right against the grain to go into the filesharing thing.”

Sealand is currently prized at 750 million euros, which equals nearly one billion US dollars, a sum of money that would be impossible for The Pirate Bay to raise anyway. Prince Michael said that maybe some wealthy Russian, who doesn't want to have a radioactive isotope dropped in his cornflakes when he's not looking, might be a potential buyer instead.

Sealand's Spanish estate agent, the one who came up with the price, also said that The Pirate Bay may not be allowed to buy the micronation, because Sealand has pledged not to allow a sale that would damage the interests of, or act against the UK.
