Absolutely. I wasn't trying to imply Valve wouldn't offer VACnet to others. I'm sure they'd be happy to partner up with other devs. My point was more that other devs probably aren't interesting because of how hard it would be the implement. Like you said Dota and CS have different implementations and I imagine deadlock does too. I imagine most games would end up with either a custom implementation or a custom model, both require a significant work on the developers side. It's probably easier to add something like EAC than VACnet so devs most likely go that route.
