your confusion may stem from the fact that i mistook the original analogy. they were calling the shirt into question. my response was calling the model into question. my mistake should be clear if you read both posts carefully. i will elaborate just in case.
every photo on Facebook is user generated. an overwhelming majority of them are bad photos. Facebook is completely aware of this.
as such, it would be an irresponsible design choice for Facebook to create such a huge presence for those photos, like the design proposal does. likewise, it is irresponsible of the proposal author to only use high resolution stock photos of decent looking people for their design.
perhaps my original post was not crystal clear. in retrospect i maintain that it was a fine explanation, albeit terse- and out of context given my misinterpretation. regardless of my post's clarity, your response makes you sound like a dick.
