I see a business model where "we're done, this one is (finally) good enough and now we'll stop bleeding cash on the training and turn up the screws on the customers we've hooked on loss leader pricing." Open weight models will never stop training for improvement, the costs for training seem to be inexorably falling, and any business model built on the idea that they can kick back and roll in the profits after their initial "hard work" is going to lose all their customers to better products.
This isn't some captive market like US automobile customers who have no choice but the limited selection of crap, crap and more crap that is put in front of them. At least not as long as the internet remains relatively open.
