There is a lot of shade being thrown against Adafruit in this discussion thread which is disappointing.
It is disappointing because it distracts from the discussion around Open Source and Arduino as a long term educational tool. Regardless if that shade is in good faith or not, it distracts from the conversation we should be having.
Yeah, let's not forget that Arduino was built on a history of being kinda sheisty: https://en.wikipedia.org/wiki/Arduino#History
And Adafruit has been a stalwart of open hardware advocacy. If it were anyone else, I might entertain the idea that they're "just trying to drum up some marketing." But we're talking about Limor "LadyAda" Fried here. She's good people and always has been. Her opinion should count for a lot.
