I don't have FULL context, because from the start I have not seen what has fandom pissing itself with joy about IDW comics, but yes, apparently the mech Megatron "cured" has been positioned as the Cybertronian version of an alcoholic. Which I guess justifies physical/mental alterations without consent, and makes Megatron a "good" leader. Where I read it as making Megatron the exact kind of power-tripping, violating asshole he supposedly was rebelling AGAINST at the start of the war (only I suspect that canon, like the fans, is oblivious to that).

Edit: Not to mention the "four million years of practice". Megatron has apparently been beating his will into his troops for the entire length of the war.
