This is ridiculous. If you truly wanted to help them, you honestly wouldn't mind if they watched their cs. Instead, you're trying to hide your selfish ulterior motives by justifying how you're helping them in the process.
"You don't deserve any cs" cause of you're trying to farm unsynced bonuses off them? They paid for the game, they're entitled to the perks, story/lore, and any content that this game provides - If they wanna watch their cutscenes, that's up to them.
I'm amazed at how blatantly selfish you are. If you know that there's gonna be some downtime with the cs, go find something else to do during that period instead of complaining.
