Ranked in these QuestionsQuestion Ranking
Pro No "Management Engine" backdoor
Gluglug avoids post-2008 Intel chipsets due to the proprietary "Management Engine" which allows remote access to the computer (including the screen, RAM, and storage), and has been exploited to develop low-level rootkits.
Pro Runs Libreboot
The bootloader is totally free from proprietary blobs, giving you total control over what runs on your system.
Pro FSF Respects Your Freedom certified
Gluglugs laptops have been FSF Respects Your Freedom certified since Dec. 2013.
