I can understand HP wanting to prevent their customers from being conned into buying false cartridges, or wanting to ensure the best possible experience for customers. But. Is it not enough to bring up a dialogue or warning telling the user it's false and they are breaking warranty, rather than outright disabling the cartridge? This seems like HP is acting anti-competitively, such that a third party would struggle to…
Nope; their business model is cartridges and ink, not so much printers. 3rd party cartridges impacts their bottom line. There's a few companies who have consumables as their business model, Keurig is another that added "DRM"-like features to their stuff. Juicero tried it with an extremely overbuilt, but ultimately stupid device with overpriced bags of fruit as the consumables.
