Are there any legal issues with GPL 2.0? Is it safe for me to use?
There is absolutely no problem in using a product licensed under GPL 2.0. Issues with GPL (or AGPL) licenses are mostly related with the fact that different people assign different interpretations on the meaning of the term “derivate work” used in these licenses. Due to this, some people believe that there is a risk in just using software under GPL or AGPL licenses (even without modifying it).
For the avoidance of doubt, the owners of this software licensed under an GPL 2.0 license
wish to make a clarifying public statement as follows:
Please note that software derived as a result of modifying the source code of this software in order to fix a bug or incorporate enhancements is considered a derivative work of the product. Software that merely uses or aggregates (i.e. links to) an otherwise unmodified version of existing software is not considered a derivative work, and therefore it does not need to be released as under the same license, or even released as open source.
