Why did Chris Quinn, editor of cleveland.com/The Plain Dealer, decide to personally write the 'Our Sherwin-Williams Dilemma' series?

Chris Quinn decided to personally write the five-part series because lead paint's ongoing harm to Cleveland's children compelled him to act—not only to highlight Sherwin-Williams' historical role in spreading lead paint, but also to advocate for the company's leadership in finding a solution; he expressed deep frustration with the city's inaction on lead poisoning, calling it Cleveland's most critical challenge, far surpassing other local issues.

What is the central focus and purpose of the 'Our Sherwin-Williams Dilemma' series according to editor Chris Quinn?

The central focus of the series is Sherwin-Williams' historical role in spreading lead paint, and its purpose—according to Quinn—is twofold: to hold the company accountable for that legacy, and to urge its leadership in helping solve the continuing crisis of lead poisoning harming Cleveland's children; Quinn framed this as a moral imperative driven by the city's failure to address what he identifies as its most critical challenge.
