Prediction:

Color me pessimistic, but it's obviously not going to be the entire picture. This explanation is going to live that sort of vague truth/lie land that the majority of news today exists.

It will instill confidence amongst less tech-savvy people, by "putting it out there" that TikTok is actually magnanimous in releasing it's secret sauce.

If by some magic they do release the real thing, it will be gamed so quickly that it will be rendered moot.

If I were them, I would do the second. That way you'll release the truth (at that time) and reap the benefits of good PR.

edit: grammar.
