SAM is the main character in this game (kind of spoilers)

You could have made the very same argument in favor of EDI relative to Shepard in 2 and 3, based on this logic

OP somewhat reminds me of  

This is just one big advertisement for new Musk's project pretending to be a game. I'm telling you.
Unfit for the job you got? Sam will tell you what to do.
Have no idea how to turn something on? Let Sam handle it.
Barely speak your own language, but got your hands on some alien manga? Sam just needs a few minutes to learn and translate it.
Nature wasn't kind on your health? Sam will pump you up.
Constantly catching flu during winter? Sam can make sure you'll never get too cold.
Something is broken and the only thing you see is that it's apparently on fire? Just scan the damn thing, Sam holds all the expertise you need.
Remember when someone stole your favorite pencil in school ten years ago? Thanks to Sam justice will be served, just scan your old desk and Sam will find the culprit. Like literally where he is right now.
Install Sam today and all the puzzles of universe won't be puzzles anymore.*

Yeah SAM pretty much is always there to bail you out of any situation you can't handle. On that we agree...but that doesn't make them the main character. Main character is simply the POV from which we are supposed to see through or the focal point of the cast of characters.

Your main character can be a complete useless dumbass that wouldn't make it 10 feet without their sidekick or supporting cast...but they're still the main character.
