This seems to me to be the simple story of "capitalism, having learned from the past, undertands that free/open source is actually advantageous for the little guys." Which is to say, "everyone" knows that this stuff has a lot of potential. Everyone is also used to what often happens in tech, which is outrageous winner-take-all scale effects. Everyone ALSO knows that there's almost certainly little MARGINAL difference between what the big guys will be able to do and and what the little guys can do on their own ESPECIALLY if they essentially 'pool their knowledge.' So, I suppose it's the whole industry collectively and subconsciously preventing e.g. OpenAI/ChatGPT becoming the Microsoft of AI.
