You still have controls over your work and permissions to others to use it. As it says on CC website about this license:
This license lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms. This license is often compared to "copyleft" free and open source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use. This is the license used by Wikipedia, and is recommended for materials that would benefit from incorporating content from Wikipedia and similarly licensed projects.
A Creative Commons license is based on copyright. CC licenses apply to works that are protected by copyright law. The kinds of works that are protected by copyright law are books, websites, blogs, photographs, films, videos, songs and other audio & visual recordings, for example. Software programs are also protected by copyright but, as explained below, we do not recommend that you apply a Creative Commons license to software code.
Creative Commons licenses give you the ability to dictate how others may exercise your copyright rights--such as the right of others to copy your work, make derivative works or adaptations of your work, to distribute your work and/or make money from your work. They do not give you the ability to restrict anything that is otherwise permitted by exceptions or limitations to copyright--including, importantly, fair use or fair dealing--nor do they give you the ability to control anything that is not protected by copyright law, such as facts and ideas.
We'll see how it works.
