Reading comprehension is a lost art i see in no where was it stated that cutting a the stream was done because of the families and friends especially solely but you need to be especially thick to reason that this isn't a consideration not to mention a benefit.

In an emergency situation it's pretty common to shut down all non official communications and direct everything through the contingency execution channels as well as to clear all non essential personnel from the room and stop all non essential activities this includes activities such as streaming and posting on instagram to the dismay of millennials everywhere.

It takes a special kind of person to think that the only reason people cut the stream during emergency is because they are trying to cover their asses, these people have dedicated their life to a job that isn't glamorous, doesn't pay well even in the US yet alone russia so yes they care about their colleagues and the people who they send up to space it's not that big of a club.

And it's in no way presumptuous to think that families and friends of those who were in the capsule might not want the world to see the events as they unfold in real time in case the worst happens. I don't think you'll find many people that would say yes I would like the screams of my loved one to be broadcast live as the spacecraft they are in crashes into a mist of fire and debris on the ground.

So yes congrats for managing to create a troll account for a single purpose of telling me exactly how wrong i was.

You may want to reread OPs comment - it mentions nothing of withholding information from the family, nor what they themselves want to hear.
