completely useless move. there are already tons of good clients for Ollama. The Ollama devs need to focus on being a better llama.cpp, not building clients.
Ollama is a VC funded company that ultimately needs a revenue model they serve investors, not open source developers. Llama.cpp is a means to an end to them, not the goal. It's hard to monetize open source libraries. But a good chat client might lead to paying enterprise users.
Running good enough models locally is appealing to a lot of people and kind of hard if you are not a developer. If you are it's easy (been there done that). That's the core premise of the company. Their tech is of course widely used and for a while they've been focusing just on getting it to that stage. But that's never going to add up to revenue. So, they need to productize what they have.
