Do you see that as okay?
Next, suppose Russia or China supported an independent actor who did the same.
Is that okay?
Now, remember, these are foreign actors with their own agendas. They may have very good reason to, say, doctor the releases or groom them in a way that best serves their interests.
So, on the one hand, one could argue that information should be free, transparency is important, etc, etc. Ultimately, they're doing everyone a service.
On the other, there is a legitimate question about nations and foreign actors meddling in a sovereign state's electoral process, and the precedent that sets regarding international norms and established codes of conduct.
It's not a black-and-white issue by any means.
