I strongly disagree with this, and I have some real world evidence to backup my point of view that companies want customers to take advantage of these policies. Walmart has a feature in their app called Savings Catcher. When you buy something from there, you simply hold the receipt's bar code under your phone's camera for a few seconds. They automatically keep track of the prices of every single item you bought. When prices drop within the policy period, it is added to your Savings Catcher balance, which can be transferred to a virtual Walmart gift card for spending at any time the customer chooses.

If one of the world's largest retailers finds value in automating this process for their own customers, I can't imagine that other companies with this exact policy in place have a problem with people taking advantage of it.
