But in this case there were other suppliers and they buy all those parts to be exclusive sellers, and for a thing (a plane) that is expected to have a long life.
And still it's much more easy on the client than having a propertary chip with planned obsolescence (print 2,000 pages, or be cycled on-off 200 times, or wait 497 days, or be moved to another table 7 times, whatever happens first) and then fail without any trace on where was the wrongdoing of the costumer.
And then have no third-party suppliers. And then charge 80% of the equipament for just one part that was made to be replaceable.
I'm not talking for how long should HP, in my case, should store replacement parts, and I know that it implies some costs.
What I consider the giant problem is that we complain that the environment is getting polluted but companies are allowed to sell things that will last just some choosen time. That we buy something but we don't own it since nobody knows when or why it will fail. I'm ok with a plastic breaking, with a chip releasing the magic smoke.
I'm mad with a chip stop working for unknown reasons because it was designed to. I'm mad that I (or anybody else) can't fix it because programing it to fail after x pages is even copyrighted and the pokerfaced company says it is to protect me from hackers, from printing bad-looking pages, from spitting some ink in my desk...
When I pay for something I'm giving my money so that the company uses it as they wish. But in return I'm just getting that I don't own, that I can't use as I want, and even is against the law if I try, because I'll be breaking some IP if I make my own chip.
Anyone following the future of Java and how using the same method/signature/name for functions/API calling (whatever the name it takes) knows how it affects us, and can imagine how this can extends to the same reasoning when one company began claiming that "I have rights on the specific sequence of voltages that are applied to each pins of this print head, so anyone else can't make the same thing".
