You must remember that we are too stupid to be able to mod the game. Only Dice devs who has an average IQ score of 230+ are smart enough to even comprehend the tools you must master to be able to mod on the frostbite engine. It is just too complicated.
The funny thing is, the tools are probably the easiest to use to date... The only problem is that they need an army of artists & coders to make so much content of this quality (and in such short time!).
I guess EA just doesn't want more independent competition. People who start modding AAA engines might get an absurd idea of making their own games, better games even, and then people might stop buying whatever recycled products and day 1 DLCs EA shoves down their throats ...
Well. at least we can hope for a future WWII reboot if this succeeds. But the feeling that we all had the first time we were amazed by BF1942 probably won't be there.
