As if large corporations base their business strategy on ethically/environmentally-minded consumer demands. At most they will propagandize or triangulate their engineering approach slightly - just enough for the media cycle to turn to some other issue. Gotta make those quarterly profits stand out!
Also - if you haven't changed a printer cartridge in 12 years than you are printing very little (which is fine, but it's not a typical use-case by which to evaluate longevity).
Other than that, definitely agree :-)
