(I really don't want to post this. Please don't let this escalate this petty 'war'.)
After watching the video and reading through both this thread and the one on SA, I would hope that it'd be obvious that he relatively just started this project. He's making a Dwarf Fortress-like (y'know, like Rogue and Roguelikes?) and, while he has a good bit accomplished so far, he's obviously very early into the project. The UI is likely one thing he wanted to show off because it's probably the feature most worked on so far. His comments have either answered questions about the project, or sarcastic pokes in response to flames.
Reading between the lines is what is getting all of these silly mixed messages. Maybe he is just making a game since he's not satisfied with Dwarf Fortress? He's clearly said that his game is inspired by Dwarf Fortress, so it's not like he's trying to take credit for the whole idea. People can like and be fans of both games at the same time. They can still donate to Toady. Heck, if this guy does go open source then he possibly won't accept donations since that may be problematic. If he is trolling the Dwarf Fortress community (which I highly doubt) then he has massively succeeded. Even disregarding the sarcastic, fake rage posts here, there are still a lot of enraged fans.
Topics like these make the Dwarf Fortress community look terrible, and make me ashamed to even post here. The guy made a Youtube video, some twits, and some posts in a thread talking about his game (I'd hardly call that a large amount of advertising) and receives a massive wave of hostility and backlash from this forum. Some of you people are treating Dwarf Fortress like it's your own game, or heck, even your first child. It's okay to be a fan of the game. To be fanatical towards it and its creator, and be offended at negative criticism or works inspired by it, is a bit too far. Even if some of the detractors of Goblin Camp say they aren't butthurt or whatever, their posts clearly speak otherwise. It's okay not to like this game, but making outrageous claims makes you and this entire community look like nothing but Toady-worshiping fanboys and girls. You don't want that.
Just... Please think before posting.

So, Goblin Camp. What will the elephants and carp of that game be like?
