No, it's not.
Again, the forums are a service Valve offers to devs. If they use it, it belongs to the dev (Valve just hosts it). Which means they are free to close it - this has never been any different.
Reviews are an integral part of Steam itself, fully independent of the dev.
You can bet your ass publishers would love to remove reviews. But they can't, because those two things are not related.
The forums are closer to the workshop than they are to the reviews.

Vavra isn't doing himself any favors being all vague about it to not spoil the story.
Which of course triggers the usual suspects even more.
