This is a big deal. Arduino has accepted 32 million in VC money and the new “Pro” boards are not open source,so they won’t be as easily cloned, and code and libraries in the ide could be unavailable to see or modify!
And I won’t be using any of these boards.
This sell out to a proprietary group is nothing new in the FOSS world. There’s plenty of examples like MySQL going to Oracle. Fork the last open version and continue marching.
