Keep this on-topic for HN: what are the technical arguments being made that attribute these acts to the same attacker, and what are the technical arguments being made that the attacker is related to the Russian government?

I'm surprised that the tech community hasn't been more vocal in demanding evidence for these claims. In 2010, Bruce Schneier was skeptical of claims that Stuxnet was created by the U.S., or even targeted a specific nuclear enrichment facility[0]. Of course, he later agreed that evidence showed it had targeted the Natanz plant[1]. This is the skeptical and scientific approach I expect from the tech community. Am I missing something the rest of the community has seen?
