In a different world maybe, but I can already see the headlines, “Mozilla open sources lackluster AI tool”. PR is unfortunately a thing, and once you miss that initial wave of interest, you’re unlikely to grab attention later without another marketing push. Mozilla is experienced in open sourcing software, so by now they’re pretty good at knowing when to do it and when not to. In other words, it says something that they chose not to do it in this case.
I had to read this like six times, because it was so illogical my brain refused to comprehend.
