That's really interesting, I had no idea they were incorporated in Ireland too and hence sometimes subject to EU law (in theory at least). Thanks for the link. I'm not actually a member, but I'd be interested to see what they produce on other people just to see what sort of data they're holding.
I believe it's done as a tax dodge, so they can book some of their income in Ireland (which has low corporate taxes). May not have fully realized the privacy-law implications at the time they set that up. Either that or the savings are enough to be worth it.
