Does enabling to run LLMs at home really strengthen democracy? People may believe that, but it potentially enables AI to run on any device with a low footprint for surveillance purposes as well, and governments don't even have to pay for the development...
If you think this is the modern-day equivalent of a printing press, it's vital to avoid this being in the hands of only one or two multi-billion-dollar corporations with a history of morally questionable moves.
If you think privacy rights and freedom from surveillance are critical to democracy, you want your smart speaker or video doorbell to do all its processing on board, without uploading recordings to the cloud. And you want your neighbour's doorbell to do the same.
And frankly, nobody goes after Microsoft Word when someone writes Xi Jinping satire using it, or ICE buy it - because people know it's a tool rather than a platform.
On the other hand, if you think ML technology is going to produce the next wave of fake amazon reviews and forum spam - you might be a lot less eager to see it in the hands of everyone.
If you think society will be slow to adapt to things like deepfakes; and that cops and corporations will immediately start using things like facial recognition technology - well, then wider access to ML might seem to have a great many downsides.
