I agree with what Rob says, until he gets to this part:

Yes, Apple shelters taxes. Yes, it’s very good at it. Yes, it sucks that they aren’t paying their fair share.

The fact is, Apple does pay its fair share. In fact, they paid billions of dollars in taxes in the US last year, more than anyone else. The fact that governments offer companies a tax break to have factories or offices in their jurisdiction is not the companies fault—they create jobs, which has great economic benefits for those regions. If you then tell a company that those tax breaks are gone, they will pick up and move somewhere else—it’s business.

This isn’t about Apple, every company works exactly the same way. This is about the way the world works.
