Russia can feel free to get lost. They do not have the right to tell everyone else what to do.

And this is so counterproductive. Does Russia think that this is going to make Finland more likely to cooperate with Russia?

But NATO and Finland had better pay some attention. Last time, Russia meant it enough to invade. (Of course, Russia invaded anyway, even though Ukraine hadn't joined NATO, and wasn't on the brink of doing so. They just were insufficiently willing to stay in Russia's orbit. So Finland is warned that they are likely next, no matter what they do.)

But Russia had also better think carefully. They are free to impose military repercussions if they choose. They are not free to escape the repercussions of the repercussions.
