HP CEO: You're 'bad investment' if you don't buy HP supplies
(www.theregister.com)
This is a most excellent place for technology news and articles.
But they're really trying with HP+ printers that come with a 3 month trial of Instant Ink. And it's not like you lose the ability to use 3rd party cartridges, because those HP+ printers already come locked down from factory. Those HP+ printers also have extra REQUIREMENTS: HP Account and internet connection.
Imagine if you needed internet connection and some account to control your lights. Oh, Philips Hue changed their ToS, so now you do.
Why internet of things is a bad idea for 500, Alex.
