> Arduino,... are not GPL based Arduino is "just" repacked gcc in a nutshell, so it is GPL-based.

  You need more than a compiler, so it is complicated, and not pure GPL, https://support.arduino.cc/hc/en-us/articles/4415094490770-Licensing-for-products-based-on-Arduino https://support.arduino.cc/hc/en-us/articles/4415094490770-L...

    I was only thinking about the software, yes. Also a lot of the "Arduino" libraries are not really owned by Arduino, even if they like to attach themself to it, so while it is true what they write about different licenses of the libraries, this what not what I considered to be part of Arduino itself. I was only thinking of the buildtools they release. While these are board specific, these are often "just" a fork of gcc, board-specific linker/image builders, a flasher and the Arduino-build system. Only the latter is what they actually created (arguable not even that: https://arduinohistory.github.io/ https://arduinohistory.github.io/).
