Do I get a license for hardware schematics and board layout and other aspects besides the bootloader? Where can I find a license in writing? If a license is not provided, I can't do anything with it besides hobby work.
Please note, I am not demanding an open-source license. Closed source projects are totally fine, I feel absolutely no entitlement to get stuff for free. I am just pointing out projects that are closed-source but disguised as open-source, thereby taking advantage of the hobbyist community. Paul may be a cool guy, but objectively that doesn't change anything.
True, board layouts aren't either, forgot about that. The circuit itself can't be copyrighted, so you do not need a license to make your own board with the same components.
I personally quite like the approach of using the bootloader chip as light DRM: The majority of the value is in software you can freely use, with licenses provided. Prototyping with a Teensy and then making a product using the same parts and the libraries, not a problem. Just if you want to provide the same easy dev-board experience you need the bootloader chip (which you can buy and use for your own design) or invest your own development of an alternative.
Yep, I really like how the bootloader works - upgrades are drag and drop. I'll write to Paul if he is open for selling the bootloader license to me for commercial use. I am sure we can come to an agreement.
That's true, at some point in the abstraction layers from Teensy to the silicon atoms, the concept of "open-source" disintegrates. But to clarify, I am mainly concerned with the top layer - gerber files, schematics, bootloader, etc.
Here is the schematic page but no mention of a license: https://www.pjrc.com/teensy/schematic.html
This is NOT open-source. It is visible-source.
