The proposal states as follows:
This proposal is a Temperature Check of the NNS governing body to better understand if there is general support for the NNS Treasury idea that has been in deliberation in several locations including Twitter and the forum.
It says that the treasury proposal wants to see if there is support for the treasury idea that has been deliberated on twitter and in that particular forum post. It is not as vague as you imply. It specifically links to what treasury idea they mean.
So I would like to reiterate on my original question: Did Dfinity consider the references as part of the proposal when assesing it? Was the information linked in the proposal considered in Dfinity’s decision-making process? After all it was explicitly specified that the links describe the idea.
