[$] GPLv2 and installation requirements
On December 24 2025, Linus Torvalds posted a strongly
worded message celebrating a ruling in
the ongoing GPL-compliance lawsuit filed
against VIZIO by the Software Freedom Conservancy (SFC). This case and
Torvalds's response have put a spotlight on an old debate over the extent
to which the source-code requirements of the GNU
General Public License (version 2) extend to keys and other data
needed to successfully install modified software on a device. It is worth
looking at whether this requirement exists, the subtleties in
interpretation that cloud the issue, and the extent to which, if any, the
SFC is demanding that information.
