Could it be to improve the sales of cartridge rechargers?

I remember in '85 exploring the options in buying a computer while stationed in Scotland. A computer magazine had a chart showing the explosion and subsequent shredding of the British Isle computer industry. Looked like an organization chart for a company in its third takeover.
Companies that were completely gone with lines leading to another company that had aquired the hardware inventory, another for the service contracts, a third for proprietary software. Some of the lines lead thru other lost companies, or to a block that indicated 'Shit Out Of Luck.' I flipped a coin and bought Apple.

My major consideration for printer purchase anymore is price of cartridge replacement, or possibility of recharge.
