@dangoodin I should also point out that the EEPROMs they embed in the plastic for DRM purposes are a large part of why almost all printer ink cartridges end up in landfill rather than plastic recycling.
they also know that "eco" models of printers that use refillable liquid ink hoppers rather than cartridges don't allow them to artificially lock consumers into their ecosystem, because you can buy the ink from whoever you like, so it benefits them greatly to spread FUD about third parties.
