There are several factors involved, but the short version is that having experienced some of the "stalking" we internet denizens tend to do when our ire is up, they are somewhat reluctant to put their privacy and sanity at risk. Additionally, they are fairly private people and have obligations outside of bitcoin that they do not necessarily wish to mix with the bitcoin world a this time.
Keep in mind, if you are not familiar with online forums and the kind of "communication" that goes on in them, especially the wild west forums like Bitcointalk.org, it can be a horrifying place to otherwise uninitiated individuals. As open and welcoming as we are, we are still an insular world that is hard to really break into, especially when you come bearing the seemingly impossible claims.
Thanks for the explanation. It is highly unusual behaviour for a company handling this amount of money and creates the type of customers (paranoid and investigative) they are trying to avoid. Probably not the best tactic from day 1, but maybe something you can't come back from.
When does my SC arrive? :>
