I also don't see how the "freetards" killed RoboVM, but you seem to agree with me that RoboVM is dead.
I personally don't like the OSS bait and switch tactic either. I prefer when companies offer other products, extensions, and/or services on top of the OSS core. If the company is still major contributors they still can shape the OSS core more suited to their proprietary offerings.
Also I kind of lost my FOSS enthusiasm, after learning the hard way if software is the product one sells, there is hardly any money to pay the bills, if the product isn't amendable to consulting and support.
We are far from the supermarket taking pull requests.
The first indicates that they unwisely picked a license that allowed their competitors to do that and hoped they would share out of the kindness of their heart, the second indicates that they failed to find people interested in working for free on their commercial product.
Maybe if they had been less generous with their competitors they would have paid them money which could have made it possible to keep it free.
So no the "freetards" didn't kill it and by using such terms instead of logical arguments you reveal the quality of your intellect.
