The Arduino corporation has been a great benefit to open source but it's also a classic trope of an advisor taking credit (and profits) for his students' work.
You're not disagreeing with parent commenter and could both be correct!
> Our investors leave free to work on whatever technology and let us open source anything we feel can contribute to the community. They never interfere
At some point, they will expect, then demand returns on their investments, then your focus will mostly be on the professional offering, while the community product gets less love.
It's not a condemnation of your as an individual or your organization: this cycle has played out many times via VC or acquisition.
What will happen if you don't make the returns they expect? Do you have a controlling share, or is it possible for them to fire you and replace you with a more compliant CEO?
This sort of thing tends to be a collaboration, until the growth doesn't meet expectations.
I'm also biased since I'm building a vc backed product as well.
Super stoked to see how your professional and enterprise offerings turn out. Do you have a public roadmap anywhere?
For some more recent boards, there are proprietary components and binary tools and blobs - notably the Expressif board packages for the ESP8266 and ESP32's. At least some of the blame for that is with the chip manufacturers and not the Arduino project.
They never interfere today, but we all know what happens when money dries up and VCs want some return on their money.
