What happens in 10, 15 years to my wwise plugin?

Question

What happens if I'm developing my Game/App what ever, and in 10-15 years lets say the Plugin is no longer supported, maybe my license runs out, or the AudioKinetic company doesnt exist
Or maybe all of the above.

Because tonight, I had the wwise plugin break itself, the wwise launcher log me out, and my packaged/compiled game would no longer launch because the wwise subsystem was not enabled. (Due to authentication)
What do big game companies do? Let's say they have an old game they still support, its using Unreal 3 or something ancient. What do they do? Do they have some special arrangement?
Is there some way to install an offline version of wwise?

Is there a way to avoid this in the future? (And i mean, FUTURE-Future)
I had to reinstall the SDK, Plugin, and rebuild the game to even open it.
Thanks,

Weston
