This is the response I have been waiting for - this kind of decisive action is a step in the right direction.
The timing however is not. This is not a preventative measure, it's reactive. Would Soylent have taken the same action if they had not been put on blast on Reddit and other sites? If not for the bad publicity I don't think they would have done anything at all.
Until they are ensuring the quality of their product from batch to batch I'm out. That means properly mixed bars, testing each batch to ensure the 100% nutritional values they claim.
