Remove unnecessary polyfill.io
#3763
Conversation

I’m wondering if we actually need the polyfills. They were required for Safari, but Safari seems to have added this feature in 2020. Do you have access to a Mac to verify? |
I only have a Apple-Silicon powered Mac thus can't install the Safari 14. But many repositories I've opened a PR to are suggesting removing the polyfill entirely, and we could do the same. On the other hand, removing the polyfill could be a breaking change though. |

Could you still test in whichever newer Safari version you have? If the feature actually works there in different languages, we can remove the polyfill altogether (we’ll just assume the information about 2020/Safari 14 is correct), Apple users will probably be on a recent version anyway. |
So I opened the MDN page on my Safari (Safari 17.4) and ran the example, it does work though.

Great, in that case, please remove the polyfill altogether :) |

Side remark: For web sites that try to comply with EU GDPR, one needs a signed written agreement of a certain kind with any CDN or similar entity, before sending traffic their way. I vividly remember a concerted effort across many dev teams to remove Google fonts from all web presences of a big German business that was my employer at the time. From a legal point of view, it is much safer to self-hosting all resources needed. |

Description
I haven't updated the
AUTHORS.txtas I though small changes like this should not qualify.The PR replaces all
polyfill.iowithcdnjs.cloudflare.com/polyfillin the docs and the template.polyfill.iowas acquired by a China-based CDN company "Funnull", see the announcement from thepolyfill.iodomain owner's Twitter and https://github.com/polyfillpolyfill/polyfill-service/issues/2834. Despite Funnull's claims of operating in the United States, the predominance of Simplified Chinese on its website suggests otherwise, and it turns out that "Funnull" is notorious for providing service for the betting and pornography industries.The original creator of the
polyfill.iohas voiced his concern on Twitter. And since the acquisition, numerous issues have emerged (polyfillpolyfill/polyfill-service#2835, polyfillpolyfill/polyfill-service#2838, alist-org/alist#6100), rendering thepolyfill.ioservice extremely unstable. Since then, Fastly (Announcement) and Cloudflare (Announcement) has hosted their own instances ofpolyfill.ioservice.
