TL;DR: Mozilla’s translation bot on Support Mozilla (that is currently overwriting user contributions is based on the closed source, copyright infringing LLM, Google Gemini. This is in spite of Mozilla claiming that they are at the forefront of open source AI, and belies their exhortations to choose to build open source AI and data sets. Although Mozilla has experience in attracting open contributions for data sets in projects like Common Voice, Mozilla is using a closed data set to overwrite open contributions. Since (paid) Gemini queries do not train the model, Mozillians can expect to correct errors every time the bot automatically updates an article.
I don’t necessarily disagree on the complexity point, but I don’t think breaking up the functionality of a web browser fixes the issue.
Web browsers are one of those basic tools everyone who uses a computer relies upon. Breaking that up would not only lead to user frustration, I think it’d introduce brand new territories bad actors like Google could monopolize. Now that unified “web browsers” exist it’s incredibly difficult to ask users to stop using them. It turns from “download this program” to “download these four or five separate programs and follow this guide to learn how to daisy chain them together into a browser equivalent.”. That’s a reasonable ask for some people. Hell, it’s a reasonable ask for me frankly. But your average user isn’t going to have the time nor the patience to attempt to make that solution work.
