An honor!
Many different reasons, but for now this is a “just me” thing. Maybe down the road when I have self-hosted Git infra (really hoping ATProto works out) I would consider accepting contributions from a small number of trusted people, if those people are willing to follow some rules. For the time being I don’t want to worry about it.
This is not true (copyright is automatic), but it won’t matter once we move to alpha because then there won’t be any copyright 
It’s just me for now! “Our” is being used in a professional sense to reflect that I consider this to be the work of an organization, even if that organization is currently just me. There will be commercial products in the future; Hobbes is part of the tooling I’m building out to support those products. I am very interested in sovereignty.
And yes that is my (“Our”) website, which is currently just a blog. Which I will be posting to more regularly now, so grab the RSS if you’re interested in that!
