Why can't it be posted publicly instead of having to trust yet another person?
The information about investors was never public (aside of the total raised, but that is needed for token allocation), and it certainly won't be made public because there are a few disgruntled individuals that anonymously wrote some bad words.
If I was one of the NVO bagholders I'd be furious. I think they're entitled to proper communication.
And they have been receiving that, via the NVO TG channel. Plus, there is nothing really to convey from my end: Vote is in progress; decision is made by current holders based on the vote (which is currently in favor of a refund using the existing balance). It's as simple as that.
