Some further clarification on the closed source thing from their FAQ:
Why is Magic Earth free? What is the business model?
Magic Earth is free for all our end-users but we also have a paid Magic Earth SDK for business partners. For instance Selectric.de (a supplier for navigation solutions for ambulances and fire trucks), Smarter AI (developing ADAS systems) or Absolute Cycling (using the platform on bicycles). For more info on the SDK, you can check magiclane.com.
Will Magic Earth be Open Source?
No; since it is also used commercially (we have a paid Magic Earth SDK for business partners), we cannot make the code public.
