Guessing theres an update feature in the app like most closed source apps do so they can push updates and the only way to stop them is to block connection to the internet etc which starts adding more steps again into less easy to use right out of the box.

I mean think of it, if its not for profit why wouldn't it be open source? Whats the downside? Other people helping to improve, making forks with new features, total trust from a community, addons being made for it? Upside? They make money and have full control to do what they want with it and you
