If you go onto subreddit for Soylent/soylent, you'll find people have very strong takes about which version was the best and why. If customers aren't happy with an update, or if they think they can do it better themselves, they'll sometimes take to mixing their own DIY soylent blends. You'll find people who swear by Schmilk or the keto diet version, Ketolent, or the French knockoff, Feed, or the Canadian chocolate version, Hol Food. There's even an organic version, Ambronite, that costs three times as much.
