I don't think it's insulting them to call them idiots for the way they ended the game though. In this case they deserved it. Now if you personally slandered them well of course you would go to far.
Even if they were short on time it doesn't excuse the atrocity they came up with and that they tried to pass it off as a "high level" of writing. Especially since they already had given many interview saying that it wouldn't be about space magic in the end. If all the leaks are true then the other writers were against the ideas but they ignored their feebacks and went along with their plan anyway. Now that is stupid too.
It might not be that cut and dry. Casey had to be the one making the "hard" decisions. The choice to actually go with the current might not have been a choice. They had to go gold, they could not push the release date. They had to have a finale and that's all they could do in a minimal amount of time. These are the kind of decisions that happen every day in this industry. I give Mr.Hudson the benefit of the doubt. He's the one who pushed for ME1, created ME2 and was there for ME3. We'll never know if he's satisfied but I like to think that he's honest with himself.
tl:dr I still believe that Hudson is a good guy.
I believe in the indoctrination theory so much as it could be true, and is still way better than what we got, even if it isn't likely that it is. I think a lot of people actually fall into taht camp, but I wouldn't say 'I believe in the indoc theory' without being able to attach qualifiers to it.
I honestly don't mind anyone believing in it. I just believe that Bioware will not fix the ending to the extent that most fans want. I'm just done, I don't want to expect anything to just be disappointed again.
That's why the Indoc theory is insane. It's just setting you up for more tears.
