I didn't think the issue was third parties casually photographing the decor. I thought the issue (supposedly) was that a licensed tiki mask design created by Oceanic Arts had been copied onto a t-shirt by a licensee (Disney) who intended to sell it for their own financial gain, presumably in violation of an applicable licensing agreement that governed the permissible uses of the design. While I have no idea if that's the "real" reason the shirts in question were destroyed, this type of thing happens -- and results in cease-and-desist letters, and failing that, litigation, with destruction of the infringing merchandise being ordered or agreed-to -- pretty frequently.
