What is the out-of-universe reason Bumblebee lost his voice in Fall of Cybertron? (It's his starting state: not an event that occurs mid-story.)
I was originally curious what the in-universe reason was, but that's apparently answered already here on TFormers.com.
Now I'm curious why this was decided upon out-of-universe.
The cynic in me thinks this was to align the War for/Fall of Cybertron universe with the
loathsome Bayverse. I'm tempted to go on a rant on how unnecessary and detrimental that was to an otherwise well-done, loving homage to the G1 Transformers, but I'll stop myself short.
