Why would you be pleasantly surprised? They have a product that's making people sick - telling you not to eat it is literally the bare minimum they could do. They haven't even issued a recall, given refunds...
It's not clear why they're getting sick or what percentage of people are getting sick. It's good they're taking it seriously and being cautious.
"Our tests all came back negative for food pathogens, toxins or outside contamination,” so it's possible that it affects just a few people but they're still be being careful.
And frankly in this case refunds are implied, I would imagine that they would be sued into oblivion otherwise.
I just think it's good to see a company take things seriously and act rather than engage in PR. E.g. Theranos, Samsung etc.
They'll give you a refund for basically any reason. Just email them and say "I don't like it" and they'll give you a refund. You don't even have to ship it back.
That's always been the refund policy, by the way, it's not related to this incident.
