So just to jump back to the "The article they were distributing is pretty clearly about diabetes" thing mere comments ago - this seems to be about budgets and administrative matters. Those are generic concerns. In fact, in my unhumble opinion, this looks a lot like the sort of document written by someone with poor marketing skills worried that their budget is going to get cut in the near future. Especially since the conference organisers didn't think there was special merit to it.
There isn't much (if any) research here. It can reasonably be said to be out of scope for a diabetes conference if the organisers don't want to include it. All of us would like a larger budget, we don't need to listen to other people present on the topic of how they also want larger budgets. That is a political topic.
