在 2 月 24 号创建者告诉大家不要使用 polyfill.io ，推文链接是： https://twitter.com/triblondon/status/1761852117579427975
然后 Polyfill.io 背后的仓库也有相关讨论：
https://github.com/polyfillpolyfill/polyfill-service/issues/2834
同时这个网站说它被中国公司收购了 ：
As of February 24, 2024, cdn.polyfill.io, the domain hosting the polyfill.io JavaScript library, has been acquired by a Chinese company named Funnull. Polyfill.io is a widely used JavaScript library integrated into many of the world's most well known web applications. All polyfill.io traffic is now pointing to the Baishan Cloud CDN ( https://www.baishancloud.com/).
看着很多移除 polyfill.io ，有无老哥真相一波，已经准备切换到 cloudflare 提供的 polyfill
