The long and short is:

Vizio put a bunch of GPL’d software on their TVs in compiled/binary form only in violation of the terms of the GPL. the Software Freedom Conservancy is suing Vizio to force them to follow the terms of the GPL and release the source code of said GPL’d software. The courts seem quite sympathetic to the SFC’s arguments. And if the SFC wins, we can expect 1) a FOSS Linux distribution for smart TV’s (think OpenWRT but for smart TVs) and 2) moving forward, demands for GPL compliance to consumer electronics manufacturers from regular folks like you and me will have more “teeth” than they did previously, potentially resulting in a proliferation of new FOSS distributions for various consumer electronic devices.
