Are you referring to the fake problems with the delicious snack bars? Or something else? I don't keep close track of Soylent as I only consume their products now and then (its shelf life is one of the things I love about it... and now I fear they'll cut that because it stunts repeat sales and encourages the kind of consumer they don't want) but that's the last I know of. Was bummed when they discontinued them, I ate loads of them and never had an issue. When they accepted returns and proceeded to eat them to prove they were fine, I appreciated that response and felt it the appropriate one but I know they backed off of that and apologized.
Not particularly - I never kept up with the snack bar controversy enough to even know what the complaint was.
I was thinking foremost of the mold issues with liquid Soylent. That's fairly old (12+ months?) and seems to be solved, but it's a long-term reputation problem in the same sense as Chipotle. Less crucially, I'm also thinking about the digestive issues people have reported - that some people talk about nausea and terrible gas when consuming lots of Soylent.
Neither of those things seems to be a "our product is nonviable today" issue, but both have raised a specter among the people I talk to of "Soylent is weird and maybe not healthy". Swapping the CEO to someone more mainstream seems like one step towards fighting that perception.
