From BHG's point of view, these people are just bots that allow KA to find a match in world war.
The only people pissed off are the people who have paid to play the game. The people who use all the hacks and exploits wouldn't have bought anything from BHG anyway, so there's no lost revenue for them.
There will only be lost revenue if the real money spenders stop buying stuff. If not, the status quo is good for BHG, it expands the players pool because there is no way to get enough space age players otherwise. The game is 4 years old, it's impossible to expand the players' base in a regular fashion. And no one is going to spend $10k or more to catch up.
And all in all, the game is heading towards end of life. Decreasing number of active players in late ages, decreasing revenue overall for BHG, lack of new R&D for new patches/ages.
