They probably didn't even think about that. Admittedly, 4GB is quite big, but if I were in their shoes, I would have expected that people are thrilled about using a local LLM instead of sending data to a cloud-based LLM.
I am still stunned that there are people who hate AI so much that they have a problem with the weights of an LLM being on their computer. To me, that sounds rather esoteric.
