Context?

I am not sure what the precise context is here. But if the context is having hundreds of thousands of people test software that is known not to work at all, then you aren't going to get much useful feedback. In many projects there is a "latest software that passed basic automated tests" tree, which may be subtly broken but will at least partially work. I don't see any point in having hundreds of thousands of people test anything newer than that; having a thousand "nothing works" bug reports show up at the same time doesn't really help anyone.
