Does this even count? Not even running on an open core written to FPGA using Foss tooling 😉
Just wanted to say my experience running a Librem 5 was amazing until I realized my social groups are religiously against texting or using anything besides Snapchat.
Also ran a PPP for a while but it seemed harder to stabilize for me at the time.
Been running FOSS everything else except for some firmware, bios, microcode, silicon, etc for many years now with no complaints. Sometimes I purposely chose hardware that is supported though so I suppose I have tailored my experience.
