Where did the author get the info that this is open source? I haven't seen Unity state anywhere that this tool we be open source.

I could see them giving source code to people who pay for some enterprise license, but I doubt it will be open source. At least not the part that extracts data from BIM software.

Haven't found any price/release model information at all either.

That is correct, the article should not be using that term.
