I use Linux and maintain my own Linux distribution. All software I directly touch and rely on is Open Source and does not spy on me. I do not own or use a smartphone. I do however permit the use of proprietary software for purely entertainment use cases, such as video games, but never for a -tool- that I use to do my job or live my life.

I even have a Talos workstation. Open hardware motherboard and open spec CPU both made in the US with fully open hardware. Also a Precursor which is similarly open.

I support these efforts as much as I financially can, but I admit open firmware/hardware is not a gap I have fully closed day to day. Yet. Deep down in some hardware is firmware I do not control, such as on the inside of my AMD GPUs. But I wallet-vote for those over Nvidia who require proprietary code in user space where it requires rights within my operating system.
