The weird part of the "freedom for all sentient beings" is that optimus doesn't really demonstrate that belief. 1) Megatron and Impactor implied that cybertron was not free. People like them were forced into a life of labor in the mines by the upper elites of cybertron, who were implied to be the autobots. Did optimus support this? If optimus was about freedom would he not sympathize with the decepticons? Did he intially sympathize with the decepticons but ended up forming his own faction after they became too violent/anarchist? The main problem here is a lack of a proper backstory. Optimus mentions that megatron murdered alpha trion and that alpha trion had forged a new start for reform in cybertron. But why? Did alpha trion oppose the lack of freedom in cybertron? If so why did megatron murder him? These questions can all be answered if we got proper backstory instead of snippets and one liners. 2) This is the most frustrating. When Jetfire defects and suggests implementing a bomb into his head in case of betraying the autobots, optimus had no hesitations for it. He did not fight for the freedom of life and making a choice. I knew it was probably smart and wise to do that, but optimus gave no resistance to the idea. None at all. Optimus would never do this. He literally said in the beginning that "They are not the Decepticons." but then allows this with no hesitation. And in the end, it was prowl who ended up realizing how morbid the head bomb was and it was prowl who got rid of it. Not optimus who was literally there the whole time. Not optimus who is suppose to value all life. Optimus is just a weak character in this show. What does he want really? He is fights for a better life. But what does that mean? Why continue this war? These questions, if answered, would have greatly improved his character.
