haven't followed that case although I know what happened.
What is their criticism of MWT about..do you know?

See the two links here (second one includes a video of daughter and grandson speaking, apparently the Periscope video the grandson refers to). The daughter's Twitter page is linked further down that thread.

Looking through her tweets, I noticed that she said she felt her father had "played" MWT. That was my impression too when watching those first episodes of The Investigator. I thought the programme was pouring salt in the wounds and in view of how the daughter and grandson have now responded wonder if that's essentially its main achievement.
