Hmmmm... It's beginning to look murky as mud....
It seems KS is more excited to approve/showcase products that are non-existent yet (only as renderings, or a prototype on a bench) as opposed to an already-built/already-being-sold online products.
I think some KS backers are suing because they're treating KS as an online store/pre-ordering system... and the projects they backed up took longer to develop, or didn't materialize.
Again, offering ready-made/already-made/available-online products is ZERO-RISK to KS backers, but KS doesn't seem too hot on that idea.
I'll check out Indigogo.
