However, most large companies held off on developing mitigation methods until they saw a proof-of-concept, which Spagnuolo provided with Rosetta Flash. Nvidia has acquired Arm. JSONP has been superceded by Cross-Origin Resource Sharing (CORS) which can achieve the same desired result with better security. (adsbygoogle = window.adsbygoogle || []).push({}); What am I missing?
