OSU has gotten away with a few holding calls. The one on that last drive was bad. Not sure about the conspiracy thing, but they have gotten away with some penalties.
That may be true but the calls are 1-0 against the Gophers on a play that gained 1 yard. It wasn't like the call took away a big play.
If they had called multiple holdings against the Gophers I could see the argument but not as the way things were called in the 1st half.
