  By the mid 2000s open-source hardware again became a hub of activity due to the emergence of several major open-source hardware projects and companies, such as OpenCores, RepRap (3D printing), Arduino, Adafruit, SparkFun, and Open Source Ecology. In 2007, Perens reactivated the openhardware.org website, but it is currently (February 2025) inactive. [0]

I think they should have worded this better, but what they are known for, more specifically, is pushing open source hardware forward and sticking with it on principle even though it caused many business challenges.
