Wall street journal started an investigation against Amazon in order of the allegation of Amazon using products from third parties.
That means to develop their products, Amazon uses data from third-parties. Amazon managed to get the data of the most bestelling items although it got the data not from itself but used it from other sellers. However, Amazon denied all these statements. That means Amazon uses data from third parties to sell private labeled products trying to promote the products as it were their own products.
In addition to that, this article shows that big companies such as Amazon use data from third parties in order to enhance their power and products which I think is not the right way because this shows that the company isn’t creative anymore, although creating new things is the key to succeed in the future
