Having Orion/Optimus choose the name "Autobots" to represent them actively reclaiming their body autonomy, after Sentinel systemically stole and kept it from them, was so fucking good.
Any praise for this movie's writing and themes is just not enough.
To follow up on this:
You can extend this interpretation to Sentinel’s theft of the cogs from the miners, since the story itself revolves around freedom and personal autonomy being the right of ALL sentient beings.
Sentinel just gets more evil the more I think about it.
