It isn't controversial for me. I think it's correct to make a bit of money off of it, especially after Greece lied their way into the EU with fraudulent accounting. However, GGP said that the EU more or less donated money to Greece and that is just not factually correct.
In fact, GGP is also wrong in indirectly claiming that subsidies are bad. Every country on earth gives out subsidies to its economy and as the EU acts like a country in many ways (esp. wrt trade), it should give out subsidies to its economy.
GGP just tried to bash the EU with baseless arguments, as it almost always happens in such threads.
