I think its more about making the same research available to everyone, or other things that are relatively free to distribute (like code, even though, as hinted, it does not mean that everything will be open-sourced as its written).
Although, you do make a good point. If only the most powerful companies can afford meaningful machine time, how democratized can AI be?
Equal opportunity to pay, or actually democratizing it so that anybody who wants to use it can reap the benefits?
I'm willing to bet it's not the latter, given the reliance of AI on large training corpuses and machine time.
