Why does a license matter for free software?

Free open source software licenses do put some restrictions on what can be done with the software, but generally they try to assign certain freedoms to new users of the software to help keep the software free. It is important to understand the licenses especially if you intend to sell or distribute the source code at a later date. However, most users of the software should be able to achieve their goals without being obstructed by the licenses.
