Indeed. In fact years ago I remember these sort of things were passed off as bugs. How times change!
It is also insane from an environmental point of view. I have a Deskjet D5160 so HP have almost certainly not released a firmware update for that in aeons, let alone since I last fired it up to print something. In fact I so seldom print that my worry isn't the refilled carts being detected but them drying out so far that even an isopropanol paddle can't revive them.
Where was I? Oh, right, yes, the environment! Selling equipment as a 'loss leader', such as an inkjet for £20 encourages waste, i.e. unnecessary upgrades. Skewed markets are rarely any good for the consumer or the environment.
IMHO, HP and chums should be regulated to sell the goddamn printer and make a profit there by having a competitive product for the price. Then they are free to sell their carts and try to make a profit there by having a competitive product.
HP, If some folk aren't too bothered by slightly 'downmarket' inks and re-used print heads then perhaps your cartridges are just a smidgen overpriced? By all means gouge the hell out of corporates on a service contract, until a competitor comes and outcompetes....
