EULAs have never been properly tested in court. Even the US, with it's strong connection to the software manufacturers has no court cases that actually give legal standing to EULAs, only a few that comment on certain policies within EULAs. Most other countries have less than that.
So basically, until someone can prove in court in your country that EULAs are legally enforceable, it's all in the realm of legal theory. It gets back to that old chestnut, when I buy a copy of software am I getting the software or just a license or something in between.
