push request #800020201 "Hey, Hernando, think you can push that update to Wiring now, we're paying quite a lot in support time here. The LEDs aren't blinking since you pushed that update to support EEPROM chips from the 80s"
It's the same reason Apple keeps their code to their hardware. I think it's a brillant business move, and anyone thinking of releasing low-level open-source code as a primary component of a hardware project should imitate it.
Also, did I miss the part in the article where Wiring and its boards were set up to become a huge success without Arduino's clever marketing and business plan? It seems like it was doomed to have "huge successes", like one class in one university out of thousands.
The guy should 100% get more credit, and if this happened to me I would always be a little hurt about it, but at the same time, would it be a big deal if it had never extended past a thesis somewhere? Would it matter if Arduino hadn't been a bunch of really clever people?
