I did not miss the point.
Let me rephrase it - VPN = covers your location = EA / Respawn can't tell if you are from China or not.
Another thing e.g. which I as EMEA player noticed if not mistaken like 2 seasons ago - loads of Russian speaking players started to use different Asian character names. I know that because I speak Russian and even now and then troll them, call them out and they admit / start talking to me via voice in fluent Russian while having Asian character names.
Long story short - you might want to make EA / Respawn accountable but technically it is close to impossible -> EA would need to back-track IP addresses which in EU e.g. might not even be possible because of GDPR, similarly I am quite sure China would not give access to such info to even EA. Etc.
At the end of the day - rules of the game are clear, game is also free to play, allows to switch regions, there is always option to quit.
Yelling some "wishful thinking" stuff while demanding it for "free" seems kinda pointless :)
Also in many cases people don't know the solution, so if you want something to be fixed, maybe you can also provide solution, vector towards it.
No game has been nor will be perfect, Apex is no exception, look at the forums: one person wants Apex to be less competitive, other more, one person wants it to be available in China, one is not, one is ok playing with higher ping/wants to be able to switch regions others demand regions to be locked per IP etc.
By the end of the day community makes the game = if people play with Chinese or any other players that potentially hack...that's their decision and why this game exists. If people would quit instantly, game would adjust accordingly e.g. now when matchmaking got clearly tilted towards favoring Preds and Masters (examples where there are 900k Master/Pred level players yet somehow lobbies for them contain mainly Diamonds or lower) I do tend to just quit those lobbies ASAP, take penalty if needed, for sure lose my rank points because of that but that is my choice - I will actively push against such making and create less frags for Preds/Masters until one or the other adjusts. Problem solved.
