According to information I read and saw on the website it only affects default airports. It doesn't touch any 3rd party freeware or payware airports.
Correct. The program replaces generic textures. If a developer of freeware airports used generic textures these will be affected. The upgraded airports in the Orbx regions and their FTX Global freeware packages occasionally (partly) use generic textures. These will then be replaced by the REX textures.
