Most companies don't listen, these guys did. Many times when people did the right thing, they had to go through a process first.

It would have been if they did it completely on their own, maybe even designed the system for this possible outcome from the beginning.

But it's the end result that matters. They can release the source or they can not. They chose to release it, and that's great!

It’s not a corporation anymore if it ceases to exist. Sounds like the engineers are working pro bono on this initiative.
