It's possible that BitTorrent's business model is going to change, but with the original BitTorrent, they kept the client closed source but the protocol was open, allowing for a wider variety of BitTorrent clients. It seems quite possible that they'll do the same thing for BitTorrent Chat (if not for BitTorrent sync as well), at which point an open-source client will likely be created that's compatible with the original. Either way, even if it were open source, it's new software, not stable software. Chances are almost any new software is going to be fairly leaky and buggy for some time. At the moment, I would personally trust BitTorrent chat somewhat more than Google, Microsoft, etc. to not deliberately put back-doors in their clients (not to mention it's not like those companies are claiming their stuff is end-to-end encrypted anyway, as far as I know), and I'd trust them to write higher-quality software with fewer severe exploits than many of the nascent open-source alternatives out there at the moment. That said, in a few years, I fully expect to be using something open-source for this sort of thing, whether it's Tox or TorChat or an alternative BT Chat client, and for the moment I don't plan on using any of the current "private chat" programs for anything important.
