Id say around 80% since I use a lot of foss programs and only use linux/android/openwrt/brother printers. The other 20% is random proprietary stuff like steam I guess to be generous.
Nearly 100%. All Linux and AMD. The biggest part that isn’t is BIOS. As far as programs go I can think of almost nothing I use that isn’t FOSS. I guess Discord.
A good 90% I’d say. All my devices run Linux (NixOS laptop, Ubuntu server, LineageOS phone).
Non-FOSS stuff:
AMD GPU in my Framework 16 laptop means the only unfree package on my laptop is Steam.
The proprietary apps I do run on my phone are TooGoodToGo and my bank as I’m not aware of alternatives.
I wear a Pebble Time Steel smartwatch, also not aware of any alternatives.
PS5 controller firmware has no replacement.
I don’t browse the surface web a lot and when I do I tend to disable JS, so I avoid most of the nonfree JS. I have no social media accounts besides Mastodon, Matrix, and Lemmy, which are all free :)
As an extension, all my close family runs Linux on their computers, as it ended up being lower maintenance than setting them up with Windows when time came to upgrade.
I wore a Pinetime for a while, sadly the touchscreen can’t beat the Pebble’s buttons. I’d buy a Pinetime with buttons and a non-touch reflective LCD in a heartbeat though! I was looking at BangleJS or Watchy as replacements but I’m really unsure about the durability and how usable they’d be (I need just the time and notifications, maps/navigation is a big plus tho).
I try to use FOSS as much as possible, but I am not willing to give up video games, so I do have steam installed. I also need discord for communication with friends I am playing with. I only use these two on my desktop computer. On my laptop I don’t have any proprietary software running in userspace, but of course it still has proprietary firmware blobs and proprietary UEFI firmware. I also have an old Thinkpad X220 running coreboot and with ME disabled (HAP bit set, ME technically still runs, but halts after hardware initialization) and unnecessary ME components stripped using me_cleaner. And my home server also runs coreboot with ME “disabled” and stripped but it has a BMC with proprietary supermicro firmware and an LSI HBA that also requires firmware.
Got multiple machines, but I think my most FOSS setup is a corebooted Thinkpad X230. The ME firmware was stripped, leaving it non-functional after the initialization. I replaced the WiFi card with an Atheros one that doesn’t require non-free firmware. The GPU is by Intel Ivy Bridge, so no need for proprietary driver. Currently running Debian on it.
With that said, there are some components I couldn’t get by:
the EC firmware is pretty much a blackbox, even though I was able to unlock some part to make it work with aftermarket batteries
the graphic ROM may still be proprietary (gonna have to recheck what my machine got currently) – FOSS is an option as well but with less support
even though non-functional, the ME is still on – god knows what this thing does exactly
CPU microcode
The rest of the components are pretty well-documented by the community if not by the OEMs themselves.
I would put 95% for this specific setup. However, if counting everything I got, not even close, as I need some proprietary components for living.
For example, my company gave me a newer Thinkpad to do work, which thankfully I got to install Linux on. I still have to run enterprise stuff from time to time, most of which are far from FOSS.
Framework laptop with x86 Intel CPU, running OpenBSD. All drivers are free, non-free firmware includes intel, inteldrm, iwx (intel wireless device), uvideo (webcam), vmm (virtual machine). BIOS/UEFI is closed.
Hopefully intel, inteldrm, and vmm firmware can be removed after I switch to the RISC-V mainboard that is releasing for the Framework 13 inch soon. iwx firmware can be removed as soon as OpenBSD has better atheros drivers, whenever that patch arrives (or whatever other foss wireless card comes along). uvideo firmware might be unnecessary, but I haven’t checked.
FOSS score: Medium-Low, after switching mainboard, Good.
Phone
OG Pinephone running postmarketOS. I don’t think there’s any non-free firmware (GPU maybe?). ARM64 CPU, only closed firmware I know of is the modem, which I’ve replaced with a free version here. Don’t know about the UEFI/BIOS.
FOSS score: Good, Medium if UEFI/BIOS is closed or there is non-free firmware.
Gaming
Steam Deck, x86 AMD cpu, running proprietary SteamOS. May replace the OS at some point if a good alternative comes along, as SteamOS’s immutable design and lack of real package manager besides flatpak annoys me.
FOSS score: Terrible, will always be Terrible because of all the games, even after replacing the OS.
All my computers run Linux exclusively. Gaming desktop, personal laptop, Steam Deck, work laptop, and all my servers in my home lab.
Hypervisor is XCP-ng, VMs are a mix of Ubuntu, Debian, Fedora, and some random other Linux distros for testing and experimenting.
My NAS is a TrueNAS Core box.
I’m in the process of switching my router to PFSense.
Phone is a Pixel 6a with GrapheneOS.
Email, VPN, and cloud storage is Proton.
Password manager is Bit Warden.
Office docs are all Libre Office & Only Office.
The only non-FOSS software I use constantly is Discord and Steam, and of course, most of the games I play. On my phone I have majority FOSS apps for everyday stuff, but some things are still proprietary.
