You should definitely write a post about this and detail what people can do from home to help.
You could lay out the process of contacting the appropriate people to pressure. Listing the right contact details and possibly a template to use.
This needs exposure and like you said more people need to demand an answer.
It seems impossible to get exposure on Steemit unless you are part of the main crowd, or trying to get in, or by spending money. This place has people with much more influence over things then everyone else, and sounded cool at first, but is feeling like a popularity contest.
But at least the post will be part of the blockchain and won't disappear.
I have given some thought to posting directly about this. Ideally, it would be put up as an introduceyourself by someone involved in the case; either the Dochertys themselves or David Scott who is doing the open source investigation.
Meanwhile I definitely will keep interjecting it in conversations online or off.
