Before public service, and after working on free-software languages, I also spent time inside a proprietary, closed AI stack built to address this kind of issue — at Apple, on Siri. I worked with the Siri team for six years, first on Mandarin and then on Wu, the language spoken around Shanghai. The engineers I worked with cared very deeply, but that turns out not to be the same as giving people the 4 Freedoms inside a closed stack. The attack surface is closed, you cannot get synthetic intimacy from random strangers on the internet, but it also means that the people whose particular language is involved (for example Taiwanese Hoklo — Min Nan, or Taigi, depending) have no repair loop. Siri might say "Wa be hiao gong taigi," but there is no way for someone maintaining a Taigi repository to patch their way back to Siri. That path is closed. There is no one inside the system you can write to — you can write to Tim Cook, I am sure, but there is no separate copy you can ask someone to improve with your Taigi material.
