EA stop supporting a lot of games, what will happen after that?

Okay guys so I am pretty sure that most of you already know that the EA will stop supporting a lot of games and that means that the owners of these games will not be able to play online, which is not always a problem but in the case of BF2 and other BF games this just kill the game. I've already spoke with a game advisor and he said that there will be no compensation at all ( in my case it made me quite mad, since I just bought bf2142 a month or two ago). My actual question is that: Can the EA do that? I mean if someone buys a game they must provide a service for that money. I am really upset about this because I just bought a game that  only worked for 3-4 months at max, and after that what can I do? I got a telephone number from the advisor (150 595 50) he told me I can get additional information from them but the call would cost more then the actual game (since I think it would be a short call).
