I'm so excited to see how this case turns out. I wrote up a summary of what was going on with it a while ago.

Vizio, take the hint and open up your full stack. Become the hacker’s TV. We’ll write cool stuff that you can use for free (like you’re already doing) and we’ll get to shut off your shitty telemetry in our own firmwares.

You can't override contracts terms that take priority (GPL, which you as developers already agreed to when redistributing it) with a second one (their own ToS).

GPL explicitly prohibits adding restrictions, so attempting to claim the ToS severs their GPL right is invalid because it is GPL which instead overrides that term in the ToS.

Hints? No, that's absolutely guaranteed by GPL, backed by decades of precedent. This is an open-and-shut case.

Plot twist: Vizio monitors become the new WRTG
