In 1998, Clinton signed the Digital Millennium Copyright Act, a bill championed by Barney Frank (fuck that guy, too). Under Section 1201 of the Digital Millennium Copyright Act, it's a felony, punishable by a five year prison sentence, and a $500,000 fine, to tamper with a "digital lock."
That means that if HP uses a digital lock to prevent you from using third-party ink, it's a literal crime to bypass that lock.
