So, this article is about a company called PayPal that lets people send money online. They want to start making more money by showing ads to people who use their service. To do this, they hired a smart person who used to work at Uber, another big company. This new boss will help them make and sell these ads using information about what people buy and how they spend their money. Read from source...

- The headline is misleading as it implies that PayPal is launching a new ad business "using" customer data, rather than leveraging the existing data they have on their users. This creates a negative connotation and suggests that PayPal might be exploiting or violating user privacy, which may not be the case.
- The article does not provide any details on how PayPal plans to use its customer data for advertising purposes, nor what benefits it will bring to both customers and advertisers. It also does not mention any potential challenges or risks that PayPal might face in this new venture. This makes the article seem incomplete and superficial.
- The article relies on a single source, The Wall Street Journal, without citing any other relevant or independent sources to support its claims. This reduces the credibility of the article and may indicate a lack of thorough research or investigation by the author(s).
- The article focuses mainly on the hiring of Mark Grether as the new head of PayPal Ads division, but does not explain his qualifications, experience, or vision for this new business. This makes the article seem more like a PR announcement than a journalistic report.
