This is what pushed me away from Ollama. All I wanted was to scp a model from one machine to another so I didn't have to re-download it and waste bandwidth. But Ollama makes it annoying, so I switched to llama.cpp. I did also find slightly better performance on CPU vs Ollama, likely due to compiling with -march=native.

Minor nit: I'm not aware of any license that requires improvements to be upstreamed. Even GPL just requires that you publish derivative source code under the GPL.
