We know that there will be a #bitcoin hard fork in about 80 years to fix an overflow bug. Maybe there will be a non contentious fork before then as well.

Do their terms allow the ETFs to legally choose not to follow the majority consensus, let their ETFs plummet, and pocket the real bitcoin?

 The terms state that they can choose which fork is the real bitcoin. 

 So they could say the less popular fork is the "real bitcoin" and watch it crash while the popular fork is still in their custody right?
