If you're going to say a term is highly contested you probably shouldn't use it in the next sentence as if it were established term of art:
the PDF comprises responses to a questionnaire on the nature of the highly contested term “post-internet.” This questionnaire is intended to preserve the widely varied opinions and oral histories of post-internet thought leaders throughout the world. (wince)
Hence this proposed rewording:
[T]he PDF comprises responses to a questionnaire on the nature of the highly contested term “post-internet," in order to preserve the widely varied opinions and oral histories of thought leaders [of the highly-contested term "post-internet"] throughout the world.
