I think Google or Microsoft probably would want to use LLaMa for various purposes like benchmarking and improving their own products. Check out this other condition from the license:
v. You will not use the Llama Materials or any output or results of the
Llama Materials to improve any other large language model (excluding Llama 2 or
derivative works thereof).
Just like Google scrapes the internet to improve their models, it might make sense to ingest outputs from other models to improve their models. This licensing prevents them from doing that. Using Llama to improve other LLMs is specifically forbidden, but Google will also be forbidden from using Llama to improve any other AI products they might be building.
v. You will not use the Llama Materials or any output or results of the Llama Materials to improve any other large language model (excluding Llama 2 or derivative works thereof).
