I appreciate your analysis of Stanley's containing lead. I do believe some wordage in your fact-check is askew. For example, you said 'caused' in the sentence "woman threw away her Stanley water bottle after it caused lead poisoning in her three-year-old." Which in the article you provided, isn't the case. In the article, it relayed "one woman claimed, her Stanley cup contained lead, and could potentially cause lead poisoning in her 3-year-old child." A part of the manufacturing process includes the sealing material, which contains some lead. However, that particular area is covered with durable stainless steel. I would say this article adequately describes why there are traces of lead found in Stanley cups, along with their safety measures to make sure customers are healthy and using a reliable product.
