Spectre: Why is an american legal procedure affecting european users or is GoG being overly careful?
The DMCA is the U.S. copyright laws passed in 1998 to be in compliance with the WCT treaty of 1996.
WIPO - The World Intellectual Property Organization (a division of the U.N.) adopted this treaty in 1996. It covers copyrights throughout all 191 signed member states. The DMCA was the U.S. law passed to be in compliance with this treaty. Presumably each of the other 191 countries enacted similar laws.
In short, on some level this is enacted through the U.N. and the WCT treaty. Hence, that is why it also affects Europe.
P.S. as an aside to all the talk about Stardock's negotiation tactics, I'm sure the judge was so superbly happy with Fred and Paul when on March 29, 2018 the judge issued the following order:
"IT IS HEREBY ORDERED that all parties and counsel are ORDERED to keep all past,
present and future settlement negotiations CONFIDENTIAL. All such negotiations, including all
offers and demands, shall not be disclosed to anyone other than to the parties without further order
of the Court."
I wonder why he thought that was necessary? But Fred and Paul did nothing wrong...yeah right...
