As the article states, HP has even been sued for this, yet continues to do it as it's a core part of their profits to keep people buying THEIR ink. Profit alone for the printer itself isn't worth it, they'd otherwise they'd not even bother making printers anymore, but that reoccurring revenue from ink is some sweet sweet cash. It's like google/fakebook/twits whining about people blocking ads or using encryption they can't harvest data from as their source of revenue. Worlds smallest violin.
