I'm not a fan of IDW's war origin... trying to have us sympathise with Megatron as if he is like a freedom fighter and the Autobots are portrayed as suppressive capitalist elitists.

I much prefer the more traditional, dictator commanding criminals and bullies into a battle against a peaceful utopia. Cybertron was shown as a golden age before Megatron's jealous conquest began, destroying everything, forcing citizens to take up arms against him... most of which didn't do it by choice either.
Sympathising with Megatron is like sympathising with Ned Kelly or Hitler, or any other criminal that had ambitions of power & possessions.
