The question is whether they are still actively pursuing enterprise clients. If they aren't, then I agree. If they are, then it's not putting it out to pasture, it's just a different business model. There are plenty of companies that do this. My brother works for one that does it for large network storage deployments using proprietary technology, and I imagine they don't want to hear from you unless you are willing to put out hundreds of thousands to millions of dollars on a deployment (and yet they still have new deployments). I definitely wouldn't consider them putting the technology out to pasture because of that.
