The CofS has shown that its willing to change the material to some extent, some indies are violently against this but I believe it to be something that needs to be taken even further. It's not that the CofS views someone else as source, its that they are willing to ignore the idea of LRH as source to make improvements - even if those improvements are only <1% of the ones I think need to be made. Not all indies are this way by any means, but its a common sentiment that I encountered. There is at least one website which goes through many (if not all) of the GAT changes but I can't find it offhand. A little googling around should bring it up though. When I went through it though I didn't find one change I wouldn't have made myself. Now the topic of making people redo the bridge after the GAT releases is a different story. I think that is dumb and had I paid hundreds of thousands of dollars to do the bridge I would have laughed at them if they said I needed to do it again.
