Yeah, the move of certain international flights to T2 seems like a minus for many passengers, especially those connecting between North America and TSA/SHA/HKG who will now have to change terminals. Not to mention the potential confusion around which terminal to go to. I guess it's nice for people making domestic-international transfers but that's about it...
Also, the author of that article seems to think that all of T2 was closed during the pandemic, when in reality it was just the small international section that was closed.
