Can I modify and distribute free software for commercial purposes?

Yes, you can modify and distribute free software for commercial purposes. Free software, as defined by the Free Software Foundation, offers users the freedom to use, study, modify, and distribute the software. This means you are permitted to make changes to the software's source code and distribute the modified version. You can also distribute the original or modified software to others, whether for free or for a fee. However, it is essential to ensure that any distribution includes the same freedoms and rights that the original software provides. This means you must preserve the software's free status and provide access to the source code, allowing others to exercise their freedoms.
