With how short-sighted they've proven to be, thinking solely for the now, not what's next, my guess is they're seeing enough cash come in from subscriptions and people saying they're ready to donate to the private site that they see being able to pay themselves back for the work on the KS and pay for enough staff to man the website (by the sounds of it they had to bring people in to do the website, so 'adding more team members' could really be talking about the people they already owe for the website and forums).
They've run this thing, intellectually, week-to-week, so my guess is that's their typical scope financially. If they can pay the bills this week, then bring more people in because why would next week be any different?
