Note: while Walmart has potential antitrust concerns, it's due to how they impose pricing demands on suppliers, and possibly for their online marketplace. The fact that they sell store brands in their retail locations is immaterial, as that has been a part of retail since before third party brands existed. See, e.g., the Sears case, in which it was Sears' ability to fix prices due to its market dominance that concerned antitrust regulators. They didn't care that Sears sold store brands alongside competing products.
