In the same light there are a lot of places that it currently shouldn't go. Like a kernel.

I don't think they're all that separable. In the worst case, using a corporation's LLM, as Linus is doing, is in essence voicing support for any negative effects in the strongest way possible. LLMs as a technology are fueled by stolen and scraped content, which is in turn fueled by other myriad issues, like datamining and privacy erosion. LLMs as a technology are also extremely inefficient and resource intensive; by writing yourself off as "just one person" doing it we're ignoring the global effect of many "one persons" all consuming resources by using this technology.

I guess my point is that by using and helping to normalize LLM usage it's playing right into the hands of all the previously mentioned consequences. Big tech doesn't need you to use their specific brand of LLM, they just need you to become dependent on the idea of LLM assistance itself. Their endgoal is total adoption and mindshare, and they're spending vast amounts of money in order to reach it. By refusing to support the technology no matter how "useful" it might be, we can prevent many of the inherent problems from getting worse, and prevent big tech from gaining even more leverage over slightly important things like "is the news real".
