Oh sure, but in my defence a simple Dob eq platform hardly requires any software, so 'open source' would be a strange thing to point out ;) A lot of the hard work is the custom PC software & getting it ASCOM compatible for autoguiding, etc.

You can open source a file for use in 3D priting. Lots of work goes into creating those files, so releasing it as open source is a concious decision the maker made.
