Did they do anything about the cartridges yet? Some printers detect when cartridges have been refilled by the user and are programmed to stop working then. That's not just with HP printers, but across the board. Even at consumer level, the prices of a cartridge is criminal compared to a bottle of inkjet ink, with enough for many dozen refills.
Cartridge: $50
10 fl oz of printer ink: $12
I don't put much value on the content on Wikipedia anyway. Most of it is written by only a tiny percentage of accounts, that have so many contributions that they may well be state/corporate actors. It has come up time and again that glowies of all colors edit Wiki pages.
