Is it the same reason that Starbucks started coughing up, despite the fact that they hadn't broken any laws as they are written, the bad reputation they got was costing them business and that lost business was worth more than they would have paid tax.

So, stop buying Apple, stop using google, stop using any of these companies that are taking the piss.
We don't hear much about Microsoft? What's with them all these years and licence fees?
