I think they gave her an opportunity to respond so she wouldn't take it up with the producers in a public forum they didn't control.
And, thinking back to last year, they gave Emily a chance to reply/apologise for her comments, but there was still no chance they were letting her back in the house.
I noticed last night that when they did the voiceover about the phone voting being cancelled, they said that Channel 4 would not be making any profit off of this year's voting.
