The term "infection" in the context of software licensing typically refers to the rights and restrictions associated with using, distributing, and modifying software. Licenses governing infections are designed to protect intellectual property and ensure that creators retain control over their work while allowing appropriate use. Common types include:
1.
Proprietary Licenses
: These are restrictive and often come with specific terms, such as limitations on redistribution, modification, and commercial use. Users typically pay a license fee or adhere to usage agreements. Examples include Microsoft Windows and Adobe Creative Suite licenses.
2.
Open Source Licenses
: These licenses, like the MIT License, Apache License, and GNU General Public License (GPL), permit more flexible use. They often allow users to modify and redistribute the software freely, provided they comply with the license terms. The GPL, for instance, requires that any derivative works also be open source.
3.
Copyleft Licenses
: A subset of open-source licenses, copyleft licenses ensure that any modifications or derivative works are also released under the same license, promoting software freedom and collaboration. The GNU Affero Copyleft License (AGPL) is a notable example.
4.
Creative Commons Licenses
: While not exclusively for infections, some Creative Commons licenses can apply to software, allowing creators to specify how their work can be used, shared, and modified, often with conditions like attribution requirements.
These licenses balance the need for creators to protect their intellectual property with the benefits of open collaboration and innovation.
