I think the change that you can’t modify the code and use it yourself in production is a big change that is glossed over. ES is now free as in beer. You can look at the code but you can’t touch it or change what it does.

Edit: I was wrong about this. The license itself does not say this, but the blog post seemed to indicate that it was a change. I think it’s an exclusive inclusive or problem.
