It’s amazing what a difference a little bit of time can make: Two years after kicking off what looked to be a long-shot campaign to push back on the practice of shutting down server-dependent videogames once they’re no longer profitable, Stop Killing Games founder Ross Scott and organizer Moritz Katzner appeared in front of the European Parliament to present their case—and it seemed to go very well.

It sounds like you’re trying to “hint” at the idea that a bunch of games are using Epic Online Services and/or the Online Subsystem Steam API associated with it, but beyond that I don’t understand what point you’re trying to make.
If you’re trying to obliquely cite that as some kind of counterexample where it’s reasonable for a game’s source code to remain secret just because part of it is that library, then no, it fucking isn’t. I can’t tell whether EOS has the source code available along with the rest of the Unreal engine or not, but if not, it ought to be and IDGAF about any excuses Epic might have for not making it so.
If you are so hell bent on being right or knowing the answer. You could sign all of the Steam, Epic, and SDK NDAs to get access to all of the documentation.
LOL, what? You’re the one trying to make a point here, not me. Spit it out. I’m not gonna do your fucking work for you!
