If they lip sync, it’s out of their own volition. And yes I mean this for EXO too. And I can usually tell when exo is live.
For me it always felt like they were cognizant enough to pick and choose their battles. And as their fan I was completely okay with that because for the vast majority of the time I know they’re live. Just gotta hear ksoo ad lib to know exo is live af lol.
Anyway for me it never felt that it was “compulsion” from SM. Even during debut era exo had performances where they strained their vocals and sang mama (hello MAMA voice crack compilation ) and other times where they said fuck this shit are you kidding me gimmie that LIVE AR.
With time another thing that changed was the level of their backtrack. From lost planet to exploration you can literally hear how EXO’s backtrack sounds progressively got mellower.
I don’t want to attribute EXO’s victories and their natural maturing to just their company. It feels disrespectful tbh.
Fans need to stop putting every blame on the company IMO. An idol’s confidence and abilities also play a part.
