Don't get me wrong, I in no way would consider them wishing to turn a profit evil. Exactly my point they are business and want to turn as much profit as possible.
I am also fully aware of LFLs excellent relationship with the costuming community. I do however think Disney will want to try and push some towards licensed pieces. It is great business sense to do so. Also the way they have been pulling licences back in house for many products for Marvel tends to make me lean this way with my thinking as well. I don't think they will in any way move to close down the fan made outfits, as you say the 501st is a strong fan face and voice in the excellent charity work they do. However when anyone new hits Google for the first time I feel Disney would want a licensed vendor popping first in any search.
My original post wording is clearly wrong. That's what I get from throwing a post up first thing in the morning
