The GNU General Public License (GPL) and its “Lesser” version (LGPL) are widely known and used. Still, every so often, a networking hardware maker has to get sued to make sure everyone knows how it works.
“The favourable result of this lawsuit exemplifies the power of copyleft—granting users the freedom to modify, repair, and secure the software on their own devices,” the SFC said in a press release. “Companies like AVM receive these immense benefits themselves. This lawsuit reminded AVM that downstream users must receive those very same rights under copyleft.”
