A small stake on the order of a quarter trillion dollars
Yeah, but I don't think, that is the primary reason.
I am just trying to understand - why Google haven't done and have no plans for it. They have done it for Android and have Gemma models too.
Doesn't make sense for them to give away weights. They sell their own service using that and killing the competition (that they have a stake in) isn't in their interest either because their cloud growth is based on other companies' continuing heavy investment in this space.
