I'm not sure but I think this license also indicate that you are not responsible for any risks your program will cause after it is modified which is great, in short, I'm not to be blamed when someone modifies my code and explodes.

As to protect my investment, I will sell it with agreements and conditions. Pay me so I can rebuild my business back and to venture to a different project. This all of course depends on what is the current situation and contracts, etc.
