For years free and open-source software (FOSS) community was dreaming of fully open-source OS and firmware solutions. While fully open-source OSes are available, firmware-level software is still usually a closed-source binary. There are serious developments around firmware-level open-source software, but many of these firmware replacements still need some binary blobs know only to the hardware vendor. Company Purism wanted to reversee engineeer blobs and provide open-source alternative for modern Intel platforms. It seems Intel isn't happy about that and politely asked Purism to remove document about it's findings. Purism's FSP Reverse Engineering Effort Might Be Stalled
It sounds like their post violated some license with Intel, and so they took it down. But it doesn't sound like Intel is challenging the open-source firmware effort itself.
