JSON Formatter Chrome 확장 프로그램이 폐쇄형으로 전환되고 광고성 코드가 포함됨

A popular open-source JSON Formatter Chrome extension has transitioned to a closed-source model while inserting advertising code, exposing the vulnerability of relying on volunteer-maintained browser extensions. This incident demonstrates the growing tension between sustaining open-source projects and the commercial incentives that can compromise user trust and data privacy. Browser extension ecosystems face a critical credibility challenge when popular tools are monetized without user consent or transparency.
