Yeah, but that's not paraphrased right. I am saying if one's frame of mind is to offer a product while hoping someone doesn't notice that the product is not meaningfully different than another product except for being pricier, that's immoral. If the price difference is for convenience, that's fine, such as customer support or help setting up a product. The other posts address this part of your question well.
But the other part of your question is about what the seller is aiming to do, the motivation. The issue is offering a product and -hoping- someone doesn't notice another product is better. A virtuous type of person wouldn't need to worry and hope their customers won't see the competition, they would be able to say their product is better or worthwhile for some reason. If their customers saw the competition, it wouldn't be a threat. If a product is good, the competition is no issue, it's good on its own grounds, and a product to be proud of. The long-term consequences are related to attitude and psychological state of oneself.
This comedy sketch has a similar idea to what you're talking about.
