This is the kind of anti-consumer behavior that really pisses me off. Every company wants to do it, too--it's class warfare 101: don't let the peasants own anything, only rent it from you. The rich get richer while the poor--including their employees--get poorer (it's a statistical fact that average middle class income is dropping despite executive income increasing to record levels). They deserve whatever backlash they get, regardless of its legality.
I'll stick with open source. A little inconvenience isn't an issue when the alternative is giving money to corporate monsters dead-set on eroding individual property rights simply to expand their own ill-gotten fortunes.
