That would rather ruin the point of the frosty pet, which was that it was a limited-number pet. Not everyone can get it, it'd be quite rude towards those who spent tons of money scrambling and struggling to get one and then just let everyone who wants one get one, don't you think?
It'd be like telling the 20 or so people that got theirs "Hey I know you were promised a rare item that only you few could get but now that we've made you spend so much money trying to get one we're going to release it to everyone, LOL".
See how people might get very angry/upset/betrayed by that flip? Trustworthy people don't claim something's going to be rare/limited-number and then turn around and let everyone get it.
