My totally uninformed opinion is that they haven't, for whatever reason, had the marketing success that some other brands have. I'm aware of ZaReason because I have a laptop from them, but I've rarely seen them mentioned anywhere.

The only reason I knew about them to buy one at the time (2012) was because the founder was visiting the company I used to work for (they were attempting to establish a real presence in New Zealand then) and a workmate mentioned it to me as I think I was looking for a new laptop at the time.

Based on the statement on their website, it seems that their lineup has been shrinking and tech support has been slowing down. That doesn't suggest that they were in a healthy place, and so I guess it just took one more blow on top of that to knock them out.
