Your title doesn't reflect what was actually said in the tweet.

He was the most unbearable this year, was so glad we got rid of him quite early. He has come across as the most bitter since leaving the house, and has a totally unhealthy obsession with Helen. His eyebrows have more personality than he does.

That's true of course, but that doesn't stop the hm's reacting to the crowd reaction.
I'm not even talking about boos, I'm talking about cheers.
As far as I recall, the cheers this season have been pretty accurate.
Jale, for example, got a lot of cheers early on, but by the time she was evicted the cheers had decreased in volume.

I really think the PHM's could have logically deduced for themselves that Winston would be a fairly safe bet to stay if he was nominated.
I don't think Matthew would have been giving up a massive secret.

Did the producers force him to attack Pav and Zoe too to make the original Housemates suspicious?

Just because Matthew was not allowed to say "Put up Winston as a decoy to get Steven or Ash out" (He's thick for thinking he could do so explicitly in the first place) does not mean he was forced to pick Zoe and Pav to go up. Excuses. And if he was truly clever, he would have been able to get his idea across without resorting to using the all too commonplace "snake in the grass" cliche over and over and over. It's just filler. It says nothing, really.

I have said to my other half weeks ago that I thought it was a set up by Helen's people to get her on the show. The only way she would go on there was if she went through to the final. They had to make it look like it was a random selection ( they did for a while). The downfall has been where everyone else has had the tables turned on them except Helen...now Mathew saying he was told to say Pav....I would not put it past Danielle to say anything to get money or airtime (she seems to be getting a lot more than most)....it is always Helens team that wins...she always gets invited to the parties...doesn't get the clips shown to her of her bitching just a quote.....feeble attempt to passify the masses that producers clearly think are stupid and have contempt for....I say vote Steven and play them at their own game....contact offcom....let them look into it

How can he be forced. Rubbish. He didn't have to do the thing if he didn't want to.

Yes. I would not be in the least bit surprised to find that out. I've been thinking that for a very long time.

"he's a snake in the grass" "he's observing" and my personal favourite "he has a psychology degree"

and Matthew reckons he is intelligent, he's a little bitch?
