Sometimes a pricing strategy employed by a firm is set to satisfy demand or reflect the premium consumers are willing to pay for a product or a service and is perfectly legal. However, the firm$$s pricing approach may not be perceived as ethical by customers or other stakeholders. Examples include Cocoa Cola$$s attempt to introduce vending machines that would charge more when it was hotter outside or Turing Pharmaceuticals$$ decision to raise the price of a drug that fights parasitic infections by more than $5,000\%$ overnight.

Find an example where a company$$s pricing strategy for a particular product has been criticized by consumers or other stakeholders but is legal. Was the company merely optimizing its pricing or did it act in an unethical manner? Explain your rationale.
