Instead of us hoping for Facebook or whoever to grace us with weights for example, or having debates over copyrights, fine, let's have the US government (just like the efforts that gave us the internet ..) put together a program for national academies & labratories, research universities (such as Stanford), and private sector work together.
For example such a program can then insure that the most up to date gigantic model X has a public variant with public weights with regulations for usage by public and private interests.
And the issue of hoovering of content to create private models becomes moot, or at least far less problematic.
I would qualify your post with open source usage of the model, training algorithms and training data as well.
