This is a great statement, they confirm they're aware of the issue, they acknowledge the concerns and they set out their intention to gather the full facts whilst suspending the operation of the research in the meantime. They also acknowledge the systematic way the need to deal with this. I hope their follow up is as thorough but I want to applaud this, it's a good approach.
It doesn't take much to write a single paragraph, though. I think the quality of their response will become much more clear later.
You vastly underestimate how much effort and attention was put into writing that “single paragraph” because I promise you it sure does take much.
