The document discusses standards compatibility and challenges to standards. It provides case studies on standards compatibility issues in South Korea when Vista was released due to reliance on ActiveX, challenges with Unicode fonts in India, and examples of websites in China that use alternative payment systems like Alipay since some international services are blocked. The presentation advocates for open web standards and outlines methods to promote compatibility like helping developers, education, and outreach.
