It's 50/50, honestly. In some cases doing that is incredibly useful for the customer. The problem is when the business decides to start promoting similar, yet different items, knockoffs, etc. that "match" your profile, yet aren't what you would've wanted to originally buy. So you wind up getting steered to something that may be of lesser quality, etc. This might be the result of the company making a larger profit on the alternate item or something else.
