That is a profoundly complicated question. The simplest answer is they aren't responsible for Dean's bankruptcy, even though they might be responsible for the direct chain of events that lead to it. Walmart has caused a lot of similar events in the past.

So, my position would be: Walmart is a paperclip optimizer and a bad neighbor, and deserves to be called out for it whenever it does its thing.

Between being forced to reduce margins to meet Walmart and other grocery stores price points and then the sudden loss of 4% of their sales volume. I feel pretty comfortable in the assertion.

/me shrugs.

It's pretty trolly to draw someone into a conversation, continue to ask for responses, and then accuse them of going off on a rant?

What's trolly is to derail a conversation, repeatedly trying to get on your soapbox to parrot word association rants about a company that you agree did nothing wrong in this specific situation.
