If you consider OSs potential friends, you may like the movie "Her".

OSs are offers organizations, some may be friendlier than others. MS has shown not to care for your privacy the least bit. Apple at least tries to uphold the facade of respecting your privacy: so they probably will go to greater lengths.

Linux (+ desktop packages) otoh are closest to what I consider a does-not-skrew-me-over OS-friend. Al east they do not have a public history of sneaky deals with 3-letter agencies and/or a business model that involves me being the product.

It's not about technology but the people who create the technology. There seems to be a complete breakdown of ethics and responsibility at Microsoft (and also other large tech companies) for the sake of 'shareholder value' (or whatever the Golden Calf is they're dancing around at the moment).
