alt Hacker News>Atmel had shipped 500 million AVR flash microcontrollers, due in large part to the ecosystem created by Arduino.
How do you know the 500 million sales is due to the Arduino ecosystem?
I used to work in embedded for 10+ years and in the 4 companies I worked at so far, none of the products ever featured AVR microcontrollers. The microcontroller of choice for production was always based on the feature/cost ratio for each application, never on the "is it part of the Arduino ecosystem?" question.
Tinkering with Arduino at home, and building products for mass production, have widely different considerations.

All of the products that i've been involved with that included AVR microcontrollers are from before the Arduino platform existed. The STMicro ARM M3 chips are more capable and cheaper then the 8-bit AVRs; The Arduino IDE never factored into the decision, even at the height of its popularity.
That is the downside. you can prototype with one chip and when the concept works switch. I've worked with many projects over the years where that was done. Sometimes an intern proved it works with arduino - which wat cheap enough to buy without needing supply management, but then we did the project with 'good code' on our internal controllers. Othertimes we bought a competitor andiagain first thing switched them to our controllers. (Our controllers are designed for harsh environments which means millions of dollars spent designing the case and connectors)
If they sold 500 million microcontrollers and your workplaces never bought any, then your experience doesn't tell us anything about why the people that did buy them, bought them.
