Mozilla presents themselves as an "open community". But they are a commercial corporation bankrolled by Google, and with an oppressive organizational culture. I would interpret this post as being not just about an opportunity for their self-aggrandizement, but also Mozilla trying to whitewash its mass surveillance of users, likely used also to train some model or another, or perhaps just to feed their patronn (Alphabet)'s ad machine.
They tell us about how the farmers and native people and whateve are all happy with their chatbots and models. The major effects are a massive and ever-increasing energy use - in a time where we must cut back and economize to avoid further global warming; a massive diversion of investment capital - especially in the US; fantastic stock valuations for a few tech giants (gee, I wonder whether any of them is related to Mozilla somehow); and other effects one could survey, all more significant by far than the examples they bring.
