This news is making me much sadder than maybe it should.
Arduino is what pulled me into electronics. I have such fond memories of those old chonkers blinking LEDs. It felt like magic.
Unless they've had a major staffing and leadership shakeup, there is a zero percent chance Qualcomm is going to suddenly become some kind of open, sharing, culture. The company DNA is patent troll.
The recent joint ventures are a perfect example. I got so excited by those newish super powerful penta-whatever Qualcomm chips from Arduino a few years ago.
Then learned the chips were unobtainable outside the Arduino modules.
Complete garbage move by a garbage company.
