@Aldryic - I'm actually much more developer than marketer (although I'm not the main developer at Loading Deck) however I'm used to explaining in terms that most people can understand. You're absolutely right that there are no solid guarantees at this early stage. Solid guarantees of security are rare and often broken anyway. I'll make sure that the research will begin by looking at the liability issues and finding a clear path through them.
If no responsibility is going to be taken on your behalf due to it being free, why not just release it so that we may host it ourselves? This would make far more sense as the only ones to blame would be ourselves instead of having to reply on a third party that doesn't give two shits about it.
I find this a little offensive. I do care about the software and its users, and I am actively maintaining it despite 'opening it up'. The reason that's possible is (once again) because research is being done. For this research to work, I need to maintain full control over the system. There are also a number of other advantages of SaaS over self-hosted for me including a lower support load.
TL;DR I'm getting something out of this in a different way.
There will however be parts that are open-sourced in the near future, but open source isn't the aim here.
