While an open-source model is obviously preferable to an open-weights model, the difference between the two is much less important than the difference between an open-weights model and a proprietary model. There are much more people who are interested only in doing model inference, for which an open-weights model is sufficient to avoid the uncertainties and costs associated with a subscription, and for enabling them to make and use better model harnesses than those offered commercially (better by being more suitable for their specific needs), than people who also want to do model training, for which an open-source model would be needed.
