From a fraud perspective, it would be extremely cheap to fake downloads.
Since Chinese companies aren't audited the same way US companies are, yet they can still list on exchanges, having some outside "probable" growth metric gives more credibility to their internal numbers.
I'm not saying it's all fake. I'm just saying it wouldn't take very much resources to fake this, and ByteDance has the resources, and we don't really audit them, so I'd gladly miss out on this growth opportunity, but that's just me.
