美国司法部在谷歌反垄断案中推动禁止其向浏览器付费锁定默认搜索引擎，却令依赖该收入的Mozilla面临生存危机。谷歌年支出超260亿美元维持默认地位，法院此前已拒绝全面禁止付费，后续影响受关注。
欧盟委员会近日采取措施，要求Meta恢复WhatsApp的通用AI助手免费权限，以保护AI市场发展并防止不可逆损害。此前，Meta自2025年12月起被调查反垄断问题，因其限制其他AI服务商访问WhatsApp平台，仅允许自家AI使用。欧盟初步证据显示Meta可能违反竞争法规，并于2026年2月发布异议声明，强调可能需进一步行动。
欧盟委员会初步认定Meta限制第三方AI助手接入WhatsApp违反反垄断规定，认为其调整后的政策仍具排他性。监管机构拟要求Meta无条件恢复第三方访问权限，确保生态系统开放，并指出其收费框架自2026年起构成障碍。
OpenAI指控马斯克旗下xAI在反垄断诉讼中，故意使用阅后即焚通讯工具销毁关键证据，导致其无法提供内部文件支持索赔数十亿美元的诉求。
