It's not an attempt to deceive. It's an attempt to navigate a complex tax system. I personally have no problem with any company avoiding tax where they can. I do have a problem with governments opening up huge tax loop holes for companies to use. Of course companies will do all they can to avoid tax. It's up to governments to build fair and robust tax frameworks.
