It's never been in OpenAIs interest to make their model affordable or fast, they're actually incentivized to do the opposite as an excuse to keep the tech locked up.

I think you're mixing the two. They do have an incentive to make it affordable and fast because that increases the use cases for it, and the faster it is the cheaper it is for them, because the expense is compute time (half the time ~= half the cost).

This is absolutely why they're keeping it locked up. By simply not releasing the weights, you can't run Dalle2 locally, and yeah they don't want to do this because they want you to be locked to their platform, not running it for free locally.
