50 -To address the problems with proprietary software, the FSF primarily promotes copyleft licenses, which require that any derivative works of the software be licensed under the same terms as the original code. The term "derivative work" is legally somewhat vague, but here is a common understanding is, "If the AGPL is essential for the software to work, then the software is considered a derivative product". For example:
50 +To address the problems with proprietary software, the FSF primarily promotes copyleft licenses, which require that any derivative works of the software be licensed under the same terms as the original code. The term "derivative work" is legally somewhat vague, but here is a common understanding is: If the AGPL code is essential for the software to work, then the software is considered a derivative product. For example:

52 -* When a software needs AGPL source code directly in order to build it, that means using a AGPL licensed library or directly AGPL code into the project, its a derivate work.
52 +* When a software needs AGPL source code directly its a derivate work. that means using a AGPL licensed library or directly AGPL code into the project makes it a proprietary product.
53 53  * Another is when a software uses an external AGPL service via network.
54 54   * If the AGPL service is not essential and an optional extension to the software, then it not considered a derivative work.
55 - * If the AGPL service is essential and a mandatry part of the software, then it is considered a derivative work. For example, A vendor could come up with the idea to use AGPL code for his propieatary product, but out sources it into a s seaprate service assessible via network, so it does not use the source code. This way he tries to circumvent the license 
55 + * If the AGPL service is an essential or even a mandatry part of the software, then it is considered a derivative work. For example, A vendor could come up with the idea to use AGPL code for his propieatary product, but out sources it into a s seaprate service assessible via network, so his software does not use the source code, but does not work with it either. The proprietary product is closely coupled to the AGPL code. This attempt to circumvent the AGPL is prevented thorugh the license.

57 57  This ensures that when contributions are made to a copyleft project, or when copyleft code is directly reused in another project, the resulting work must be released under the same copyleft license. This prevents vendors from incorporating copyleft code into proprietary products, and ensures that any derivative works remain open source. In addition, copyleft licenses require that the source code be made available to users so that they can modify, build, and control the software themselves.
