Mystery box is mystery ....

Current Adobe Discover issue offers textures, but when you finally arrive at the download it's an exe, and a promo for some character named Robinson demo-ing a silly fake example of a picture taped to a crumpled paper, which is of zero use to anyone outside a community college.

Textures are files, why do textures require an exe? And where is the list & examples of said textures? I don't want a copycat tutorial, and if that's all that is here it should say so.
