In truth, U.S. law, while flawed, draws a clear line between lawful reverse engineering and criminal activity. | ||
Companies often exploit this confusion to suppress ownership rights, discourage | Companies often exploit this confusion to suppress ownership rights, discourage common repairs, and hinder interoperability under the guise of protecting security or intellectual property. The following information will clarify legal distinctions, correct the narrative, and explain why reverse engineering your own device to restore or preserve its functionality is not, and should never be, deemed a crime. | ||
In this article, "hack" or "illegal hacking" is used interchangeably for illegally hacking, or "to get into someone else's computer system without permission in order to do something illegal" ([https://dictionary.cambridge.org/dictionary/english/hack#cald4-1-3 Hack | Cambridge Dictionary]). This should not be confused with the slang "hack" that describe the act of tinkering or modifying a device (like "a hackable laptop"). | In this article, "hack" or "illegal hacking" is used interchangeably for illegally hacking, or "to get into someone else's computer system without permission in order to do something illegal" ([https://dictionary.cambridge.org/dictionary/english/hack#cald4-1-3 Hack | Cambridge Dictionary]).

'''Section 1201 of the Digital Millennium Copyright Act''' (DMCA), passed in 1998, prohibits the circumvention of ''"technological protection measures"'' (TPMs) used to control access to copyrighted works.

It also prohibits the distribution of tools designed primarily for circumvention of copyright protection measures. | ||
What makes Section 1201 controversial is that it penalizes circumvention '''regardless of whether any copyright infringement occurred'''. In other words, even if you just want to modify or fix a product you legally own, you may still be in "violation" if the manufacturer practices overreach with DRM. | What makes Section 1201 controversial is that it penalizes circumvention '''regardless of whether any copyright infringement occurred'''.
