The (consumer) printing market is just ruined. People flock to cheap printers, and manufacturers sell 'em under cost to gain market share and compensate their losses via consumables. There is a shift in the corporate market to managed printing, and honestly I believe that is the only way for printing to survive without these kind of dumb self harming tricks.
Ironically, that is what Instant Ink also is. However it is so badly communicated that people do not realise they are signing up for a subscription instead and what it means. Leading to a lot of frustration and anger when users find out that they do not own the cartridges when they cancel. The other option is to just increase the prices in order to not sell at a loss, and ditch ink cartridges in favour of ink tanks. However that's extremely unlikely as it will lead to massive loss in market share.
