PunkBuster outdated kicks

I really can not remember when this issue started. But it has been like this for way too long. This PunkBuster error:

PunkBuster kicked player xxxx (for 0 minutes) ... This PB Server Requires (A1390 C2.351) - Error loading pbag

I am fortunate that I am a player since launchday. Have had my fair share of PunkBuster related issues. But not like this. I am not getting kicked myself. But a large portion of the new players that join my server. Players that were curious about Battlefield 4. Installed the game. Play for about five minutes and then .... bonk ... kicked. After 3 of these kicks, they do not return... Shame!

The main issue: when installing the game on PC, EA doesn't bundle the most recent version of PunkBuster. 

Issue two: because new players often use the ingame browser and not Battlelog, they do not see a detailed kick reason. Thus they remain clueless why they keep getting kicked. 

My question: Why is this even an issue? What keeps EA from simply packing the correct version of PunkBuster with the installer? 

I feel bad for the new players that move on because they assume the game is broken and too old to run. Or whatever they might think is wrong. In my uninformed opinion packing the right version of a program shouldn't be that difficult..
