Stealth mode simply refers to a stage in a company's evolution, not an on-going state of operation. For example, because the company is not yet fully formed, it doesn't have a website -- nobody has made one, because it's not the most pressing thing to do right now. I don't even think the company has an official logo yet. They are basically walking and chewing gum by trying to put together their advisory board, while they also put together the details of the corporate entity. In essence most startups go through a "stealth mode" phase because many disclosable details simply do not exist. It's perfectly consistent to say "we want to do open source", but also not have prepared a logo, a website, and an overall corporate narrative.
