Just to say, working in the industry and all that. Cody's opinion holds weight because he lives and breathes Cloud when he embodies the character. He will get the scripts, he will get the animatics, he will get voice direction from people above him, he will be told how Cloud feels in a specific moment and to make sure that is reflected in his voice and so on and so forth.
I'm sure people think 'voice actor who cares' when in reality what he is an actor full stop. He becomes Cloud and because of that he has to know how Cloud thinks and feels to portray him accurately.
If he says shippers crumble under the idea of a character having deep relationships with others then he understands Cloud himself has deep relationships with everyone that aren't all romantic in nature. People try and force not only their ideas of relationships between the characters -- platonic or otherwise -- onto Cloud, but people also try and force these ideas onto the people playing these characters and other fans, and if you don't kowtow prepare to get harassed or told you aren't allowed an opinion -- all because yours doesn't align with theirs.
Cody was just having a little fun, that people were so pressed about a meme is as hilarious as it is depressing. He understands Cloud has a deep meaningful relationship with Tifa as i'm sure he understands Cloud has a deep meaningful relationship with Aerith -- both for different reasons, interpret how you want if he believes either one to be romantic. I'm sure he also understands that one doesn't invalidate the other.
The man is allowed an opinion either way, I mean he is Cloud freaking Strife. He knows the character better than me or any of you ever can or will.
