If you want to be in complete control, you need to understand the complete source code. Otherwise, you at least need to trust whoever wrote the software you're using.

Things like this may represent a violation of trust, depending on who you are, where you live, and who you perceive your adversaries to be.

I guess nobody is happy that chromium opens a undocumented network connection to transfer unknown data.

But the biggest problem is that we don't (yet) _know_ exactly why and what is happening. Fortunately we can understand it by looking at the code, and somebody will do that.

Then we can discuss if this was a violation of trust, a simple error, a useful feature etc.
