I'm inclined to say that TechBros are usually not the ones whose work they give away for free*, and they really care more about profits than anything.

* there are a multitude of ways to provide information but making sure it's useless, for AI models that usually comes in a way of providing the source code but not training data or architecture, so that you'll need to do most of the work again. A lot of them don't do even that.

Please note, this comment is off topic to the OP post and is only about your idealistic view of TechBros
