No, it doesn't necessarily mean they won't move on to something else later, but they're now living in a universe where it will always be Autodesk's job to make that harder or less obvious to them. By any means available.
I'm not sure keeping hobbyists locked to a particular platform is that useful to Autodesk, especially considering the prices they charge for higher level software.
If it wasn't Autodesk doing this, would you have the same reaction? What about Makerbot's move away from open-source?
I would have exactly the same reaction - I don't have any issues specific to Autodesk, apart from those that I've expressed here related to their 123D suite.
To be honest, I lost faith in maker culture and open hardware in general around the time MakerBot went closed hardware - not because of MakerBot themselves, but because of the way their critics were treated.
MakerBot themselves base their designs heavily on both the open hardware RepRap and open designs by other commercial manufacturers, and their head honch Bre Pettis was a big proponent of open hardware and maker culture - even publicly humiliating newbies to the community on his blog for failing to the files associated with their designs, insinuating that they were somehow undermining the maker community. [1] (In reality, they were trying to but couldn't figure out how because they used their PCB house's free proprietary software which couldn't export - we're talking a tiny hobby operation here.)
Then he went against the very principles he publicly shamed others for failing to follow and turned MakerBot's hardware and software proprietary in order to make more money.[2][3] All the people who politely but firmly criticised him for failing to live up to the same standards he held were accused of using "language similar to that we usually hear from people who blow things up" and "fundamentalism" by another maker[4]. This was linked supportively by one of the most prominent companies, Adafruit.[5] Anyone who suggested that comparing other members of the community to terrorists was incredibly inflammatory itself, or linked Bre Pettis' own views on others who took open hardware closed, was labelled a "troll" and had their comments deleted. People who correctly figured out that MakerBot was taking their hardware closed based on Bre's non-denial denial[6] were called liars and accused of spreading rumours. Remember, Bre's own public humiliation of newbies with much less power than him didn't get this kind of criticism.
So yeah. I'm basically done with open hardware and the maker community. It looks like a way of suckering people into doing big businesses' work for them and then labelling them terrorists when they ask said businesses to uphold their end of the bargain. I guess it's profitable for some though.[7]
