I don't think it is useless, but I don't think fear of imprisonment is 'reasonable' either. Hence, they are making it voluntary, only people that can't read and don't want to listen think it is being 'scraped' it isn't.
When you make any survey "voluntary," you're going to introduce a selection bias by giving the surveyed the choice of whether or not to participate.
This is actually where Pluggy's point comes into play. Unless you have an extremely high completion rate, you're not going to be able to be sure that your sample is truly random. If you can't be sure your sample is random, you can't be sure of the results. If you can't be sure of the results, what's the point?
Even if it's not being officially scrapped, it's being effectively scrapped.
