I think you should make an effort to use open source whenever possible, even if it’s the inferior option. I don’t believe this out of any ethical or moral obligation - it’s purely selfish reasons. Any proprietary code that runs on your hardware is something you don’t control. For example, we really have no idea what kind of telemetry Microsoft put into Minecraft.

You are essentially taking your hardware - something you physically own and belongs to you - and turning it into a mechanism for advancing the interests of a megacorporation. Me personally, I prefer my hardware to benefit me and me alone. I don’t want it sending data home to Microsoft so they can feed their AI models at my cost.

The more proprietary software you run, the less and less you actually own your computer.
