Not at all. I buy the cartridge. I want to maximize it's utility. Brother is artificially placing restrictions to prevent this maximal utilization. It's good for their business, but so would sending someone with a club to force me to buy more toner whether I need it or not. Somewhere there's a limit to what's sane for a company to do.

Either way, their good business is hurting my business by artificially preventing me from making maximal use of the supplies I buy. Workarounds are possible but annoying. I demand that I am allowed to actually use what I pay for without jumping through hoops.
