What bizarre review. For a product which was marketed for what he readily admits is the niche of people who want Wikipedia but don't have internet access (not even a smartphone), he wasted a hell of a lot of time whining about how it isn't as good as the online Wikipedia, or that the device isn't as good as a laptop or smartphone.
From what I can tell, when seen from the perspective of who it was for, it was an excellent piece of kit, well worth $99 (ignoring the elephant in the room that the data itself is junk, not remotely an encyclopedia). I'm intrigued as to how the parental control works, since AFAIK there is no support for such filters.
It is a good example of how private companies that perhaps believed the hype of the cult, got their fingers burnt when trying to monetise something that is over-rated even in its free state. If wasting money on this device caused the company's eventual collapse, they'd of course have no comebacks against the WMF. Just like any scam cult.
The reviewer seems to have either missed, or misinterpreted, the copyright symbol. You cannot of course copyright the content of Wikipedia, not with an all rights symbol anyway. One would presume that exists to cover the proprietary code.
Interesting that it is still being supported in terms of updates. I assumed this must be a wiki loving nerd, but having seen the update also includes a copy of ED and Unencyc, you wonder what is motivating him. Although that is one hell of a meta exercise in trolling, someone who carries water for those sites, making money out of Wikipedia. Christ knows what might be in the version he is distributing though....
I wonder if the Wikipedians will be good enough to class this reviewer as an RS, so the article about the device can be suitably updated. They care about the world staying properly informed, right?

The reviewer missed the big story here though. Wikipedia in a box is still a thing these days, it's just funded using charitable donations obtained using the reflected glow of the Wikipedia brand, and organised by people deeply connected to the cult. That device is marketed to the exact same people this presumably was.
The major flaw in these scams, is of course the Wikipedia disclaimer. That states you cannot assume anything written in it is correct. Not a word. The Wikimedia Foundation, because it doesn't want to be sued into oblivion, market their encyclopedia as only even being usable if you have an internet connection, so you can read the contents of every footnote in an article. Hard to reconcile that with the fact today's Wikipedia in a box is marketed as a medical database.
