That is true, yes, I do agree.

But, on the other hand Windows is not open source as well and I have to use it for work or an oddball proogram here and there that just doesn't run on Wine.

Hell, people also use a lot of closed source code in their Linux installs as well. Let's strat with drivers and firmware binary blobs, printer drivers (binary blobs as well, depends on manufacturer) and end with NLE software like DaVinci Resolve... we use binary blobs all the time, including our phones, and even though none of us asked for that, but instead was shoved down our throat in order to be able to live in a modern society, no one seems to complain about that... but, when a random stranger suggest using something, oh no, that thing most definitely is something malicious 😒.

Run it in a sandbox for a while, see if it calls home. If it does try to call, block it with a firewall, is that so hard 😒... though I've never seen it even try to call home or do something malicious, and as I said, I've been using it for years. Also, people use a lot of their products, I have yet to see one complaint regarding any of their products doing something malcious.
