...and you are presented with:
It is also amusing that they say they've made the change because while they believe in the Maker Movement, they also want to keep improving their free apps so they can unlock the creativity in everyone.
Well, it certainly seems fair to say that Autodesk likes free and they like the creativity of others, because as you take a look at the license agreement, you'll find licenses and copyright notices for all of the free software that Autodesk is depending on to build this application (click Help, then About):
I'll save you the time of going through this box, I cut/pasted it into Vim and I'm told it's about 8600 words long. You'll see all of the open source goodies in a minute.
Autodesk says many times in this license that they'll give you the sources if you send a CD-ROM to their legal department. I don't have much reason to believe that they won't honor this request, but I don't care enough to mail them a CD.
Now, to be fair, I don't think that Autodesk should give away their expertise -- namely decades of work on their solid modeling and CAD software -- for free. However, I do find it curious that they want to impose ownership on the physical output that was created using their software. In my opinion this type of restriction is not in the spirit of the open source licenses that Autodesk used to build 123D. And further, is it legal? Could Adobe put a claim on artwork you've made with Illustrator? Could Google put such a claim on a book you're written using Google Docs?
Legality aside, it would have been a better move, in my opinion, to not impose restrictions on the output of the free version of 123D, but then give the users good reasons to go for a paid version. Maybe even give users the full version for a month to try it out?
We are talking about a software for makers. Software for hobbyists, for tinkerers. Make it powerful, but not powerful enough to generate prints and build cars with. Adobe experimented with this concept with Adobe Photoshop Elements, a stripped down version of the professional-grade Photoshop. For $60 you could get Elements that would do almost everything most hobbyists needed. For $600 or more you could get the full-blown Photoshop. Today, even Adobe has jumped on the software-by-subscription bandwagon, giving you all sorts of cloud-based services for a monthly fee.
The trick here is, it's almost Christmas. And I think there will be a lot of 3D printers under trees this year. Dremel is jumping into the mix and their printer will even be for sale at Home Depot. So Autodesk needs to provide users with a way to get their model out of their software and into the physical world. So, they do allow you to export your model to .stl format from the free version of 123D, but I'm not sure how they would prevent you from uploading your work to Shapeways and putting it up for sale in the Shapeways store. Nevertheless, their license says you can't do that.
Here are the software licenses I mentioned earlier. I've deleted all the lines that didn't contain "portion.*related.*" to end up with this list. There are also some commercial licenses in here as well as some licenses I can't identify, and some portions that haven't given any credit. If you see a mistake here, leave a comment and I'll correct it.
