Nintendo didn't put legal pressure on emulator devs for decades at this point, which made devs less cautious about preserving their pseudonymity.

Now it's too late and they can't stop Nintendo from finding out who they are and which mistakes they did at some point over the years.

Maybe a new generation of emulator developers will be more protective of their identity, by using hosting providers like Njalla or privacy networks like i2p. The latter would limit access (as it requires i2p), which isn't desirable for most users.
