Well, if you're tying tax to the algorithm then all the money should go back to the mothership. I have no idea what the rates of tax in Ireland vs California are.

It's not that debatable - we'll see unified tax codes across the EU. Some companies (not just Google) pushed things too far and set up weird schemes that exist only to reduce tax to a minimum.

> Google is just taking advantage of that complexity.

"Taking advantage of" also has negative connotations. Exploiting.
