"Merge finances" aka combine the family jewels.

Just don't connect smart TVs to the internet. Get something cheap like a raspberry pi + wireless mouse/keyboard or an android TV box for the same functionality. (More functionality, actually)

I'd like to add the OGL they were pushing would have effectively allowed them to steal homebrew and 3rd party content. They'd reserve the right to resell this content as their own or make it disappear altogether.

This would include supplements and adventures, of course, but the way it was worded, it would even include blogs and YouTube videos, etc.

Of course this isn't a unique situation (Meta has done this forever, for example)

You could totally do something TaskMaster style.
