Just going by stats at HT it was pretty much all Celtic but watched the highlights and for the second / third week in a row there was a second half collapse. Poor finishing cost Hibs the game more than anything elseI think the first Celtic penalty could go either way to be honest. You don't see the given much, but that doesn't mean it wasn't a foul for dangerous play. If its outside the box its probably a free, but i can also see the argument that its on the soft side.
Kyogo's is pretty much a clear penalty, despite getting the shot away he's fouled after, these are usually always given nowadays.
Boyles was a dive.
From what I saw of the game Celtic were brutal and Hibs had the better chances.
Kuhn looks a flop, which isn't surprising given his career to date.
Regarding the head collision being a free kick outside the box. We had Balogan injured recently in a very similar incident but near halfway line. I honestly cannot remember if the foul was given or restarted with a drop ball
