The end goal is not adoption of FOSS licenses, the end goal was the Four Freedoms ( https://en.wikipedia.org/wiki/The_Free_Software_Definition#T... )

- The freedom to run the program as you wish, for any purpose (freedom 0).

- The freedom to study how the program works, and change it to make it do what you wish (freedom 1). Access to the source code is a precondition for this.

- The freedom to redistribute copies so you can help others (freedom 2).

- The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

Note that it "preserve licenses" and "preserve attribution" are very much not in that list. Well, the Four Freedoms are what these AI doohickeys enable by being able to in theory reverse engineer or replicate any code, making all code effectively "public", and to bypass any copyright issues around distribution. The fact that AI blowing away the existence of proprietary code also blows away the licenses of FOSS licensed code is a harmless side effect of getting to the Four Freedoms, which was the Free Software goal all along.

If any of this is surprising, then you didn't understand what you signed up for. The AI monkey's paw has curled and you've got what you asked for, sort of.
