You forgot the VAT that Facebook's UK clients have to pay, the VAT Facebook have to pay on their expenses in the UK, the council tax that they have to pay on their offices, the pension and NI contributions they have to make, etc, etc.

At the end of the day, they aren't a UK corporation, so why should their corporation tax by high?

To be honest, it's hard for me to really form an opinion on this when the information provided by the media is so superficial. For that reason I tend to share mrkmcknz's sentiment. It all smells too much of the kind of trolling that's institutionalised in the media now.
