Here's my theory... Apple has to charge money for Facetime because of accounting requirements. Something they didn't want to do, as they knew it would slow the adoption rate. Extremely easy way to get around it? Release it as a beta. Then the accounting requirements don't apply. Everyone up until today was able to download and use facetime, so I can't imagine there are that many people out there that wanted to use it, but hadn't yet downloaded it. Now, the beta still works. All of those people have a working copy of Facetime. (HD isn't needed since that only applies to new ones) Conclusion: Facetime beta wasn't actually a beta at all, it was a way for Apple to give it to everyone for free.
