I love the project, but dislike what a meaningless bullshit buzz term "open source" is nowadays (or may always have been). Tesla's open source patents, open source recipes, open source illustration ... What source is open here? The vector data? Great, I can get the source, but what does this actually mean for my use of it? Can I just use it in my projects?
I think the terms you are looking for are "royalty free" or "permissively licensed".
It was the easier way to signal what exactly unDraw was back then when it was launched and since SVG images are code, it was much cleaner than writing CC(whatever) for users to understand. It remains that way but it will be much clearer in the new version.

nope. open source isn't making anything clearer in this case. in fact using that word made me wonder what exactly the license is for this... still not exactly sure what it is.
