They've already drawn a pretty clear line for Reskate since they made a statement.
- Do not release paid content
- Do not use content that is in the game files but not yet released or not finished.
I imagine they are just watching and seeing what will happen with Reskate. It's caused the game's daily peak users to essentially triple if not quadruple, even if people are literally playing the exact same game and don't want to admit it. If Reskate puts in security measures that blocks any material that EA does not approve of, I think it will be around for a long time.
