EA's older Battlefield titles were a victim of the 2014 GameSpy shutdown, which disabled the online infrastructure for plenty of classic PC and console games. To get around that, Revive was distributing modified versions of the older Battlefield titles along with a launcher that allowed access to its own, rewritten server infrastructure. The process started with Battlefield 2 in 2014 and expanded to Battlefield 2142 last year, and Battlefield Heroes a few month ago. It's the distribution of modified copies of these now-defunct games that seems to have drawn the ire of EA's legal department. Revive claimed over 900,000 registered accounts across its games, including nearly 175,000 players for the recently revived Battlefield Heroes.
