Even When EA Acts, Cheaters Still Reign in Asia Servers

those 1, 200 cheating accounts were linked to a new type of cheat that has become harder to detect. Those 1, 200 players banned? Most likely people who bough the lowest level version of the cheat due to it being labeled as "Undetectable", as it doesn't directly operate on your pc like some cheats, and hard rage hacking. I've also seen people wall hacking and soft aimlocking everywhere at the moment also, probably also using the cheat as well. 

As for your points.

1. Yes, its PR to say they're doing something.
2. potentially but I don't think that's why there's so many cheaters I think its just an influx of people who have seen this new type of "undetectable" cheat and want to use it to feel superior to others
3. Idk how that would even work without region locking everyone, which would leave people like myself in completely dead servers or servers with even more cheaters than your own.

Solution? EA needs to invest more into their cheat protection. Will they? No that's never happening.
