Care to tell us which ones?
Accept they now actually have permissions for the mods they distribute. So by claiming they don't your spreading misinformation.
Originally the technic pack didn't have permissions because it was a mod pack that was created to be shared among some friends on the SA forums. However the yogscast covered it and became very popular, and the mod authors found out about it. Some of them had thought it was good idea, for example Eloraam (redpower, forge) others though didn't like it. Alblakas (IC) for example though they were basically stealing from him and taking credit for his mod. However he talked to the technic team, realized that they were not claiming ownership of the mods, and also that he had an increased number of donations because of the technic pack gave his permissions. Sengir (forestry) on the other had griefed anyone who had the technic launcher regardless how you got his mod.
