I am generally ok with things being proprietary if they want, and I'm mostly ok with Orion being proprietary, but I do understand peoples' issues here.

For a lot of people (even relatively geeky people), their computers end up being "an interface to use a browser". People use their browser to file their taxes, to write their documents, to manage their websites, to create websites, to look at porn, to pirate movies, to chat with their friends, to send/receive money to their bank, and a whole bunch of other things.

It would be hard to imagine a piece of software that is capable of knowing me more intimately than my primary web browser, and as Google has proven, this intimate knowledge is valuable. Companies pay boatloads of money for large quantities of personal information to target ads (and probably a bunch of other more disturbing things).

I genuinely don't think freediver is lying; I believe him when he says there's no telemetry data being sent and that it's not tracking me, but there's the sticking word: "believe". I have to trust him, which wouldn't necessarily be the case if it were FOSS.

Now, granted, I could always run Wireshark or something to ensure that there's no telemetry data being sent regularly, but that only protects you so much; for all I know, they could be taking steps to actively make it look like they're not sending data, or they could be batching up N days of data and sending it in batches so it is not as obvious that telemetry is sent.

Again, I genuinely don't think they're doing that, I believe them, but I do see peoples' points.
