The practice of removing the printer cartridge is an extension of the printer manufacturer's practice of putting partial cartridges in new printers so that you print a few pages and then have to buy a new one... which you don't discover until too late.
A partial ink cartridge can give a casual user half a year of printing, while removing the cartridge renders the device inoperable. I wouldn't call that an extension, as they advertised a free item that people expected to function until they plugged it all in and discovered they need to spend money to restore its operation.
If you can get 6 months of use out of those partial cartridges, you must not print much...
