Quebec excluded from the iTMS competition [updated]

Vincent, who lives in Quebec, has an issue with Apple and the iTMS:

Like many Mac fans, I was interested in taking part in the iTunes Music Store competition with the hope of having the lucky billionth song downloaded... Just for kicks, I decided to read the official rules, to see whether it's actually necessary to be American in order to win the grand prize. Well, it seems that it's not a requirement to be American, but for some reason, which I don't know, Quebec has been excluded (one again!) by an Apple policy. Why?! As a Canadian and a Québécois, I have a little difficulty in understanding why I can download music from the Apple Music Store, but I can't take part in this contest. Perhaps somebody has an answer?
On http://www.apple.com/itunes/1billion/rules.html you can read:
4. Eligibility. In order to be eligible, entrants must be 13 years of age or older, and a legal resident of one of the 50 United States, including Washington, D.C., Australia, Austria, Belgium, Canada (excluding the Province of Quebec), Denmark, Finland, France, Germany, Greece, Ireland, Italy, Japan, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland or the United Kingdom.

To be excluded like this is particularly annoying. We are curious to find out the reason that has justified this exception.

We have received numerous mail explaining why Quebec was not included for Apple's iTMS contest. And it is not Apple's fault but rather due to the difficulties to deal with Lotto Quebec as reported to us by Jeremy:

Hello, I live in Montreal, Quebec. To answer
Vincent's question as to why Apple excludes Quebec, lies in Quebec
laws and regulations concerning lottery and prize winnings. Apple has
nothing to do with the rules and regulations, it is Lotto Quebec, a
government owned corporation that prohibits many contests from
entering Quebec. Apple is not the first to have an issue with this.
Most american companies that have prize winnings of any sort just
exclude Quebec because it is just too much trouble to bypass the
Governments regulations and rules with Lotto Quebec. Look it up...
