Even if the wording is not changed, I can't see how anyone would use any code samples without making it their own. If I copy a bit of code, I will need to change server names, table names, etc. I may not like the varaible names the author has, so, I will change those. What remains is the concept and no one can take that away.

Changing the aggreement to clear things up is a good idea, though.
