I don't think we can say with certainty that they didn't. We know they were hacking into other voting-related systems. We know they hacked a voting systems vendor and spear-phished hundreds of election officials. And a Russian oligarch-connected investment firm bought a company that hosts Maryland's statewide voter registration, candidacy, and election management system; the online voter registration system; online ballot delivery system; and unofficial election night results website.
None of this directly confirms that votes were changed, but it's indicative of a heck of a lot of activity around our elections, and it would be very odd if they weren't making efforts toward changing votes. Possibly to the extent of having operatives in the US to do so or bribing election workers, though I have no evidence of either.
And so we can't with many other actors. Why single out Russia?

From where I am those claims have not been sufficiently proved. But yes, depending on the credibility you afford leaked NSA documents, it's a reason to focus on Russia. Still I want to caution against the conclusion that evidence of tampering means the Russian state must have done it.
> Possibly to the extent of having operatives in the US to do so or bribing election workers, though I have no evidence of either.
A classic conspiracy theory. It's nice in that it works even when the scheme is exposed as even rumors of it destabilize U.S. politics.
How is that a conspiracy theory?
> You'd think there are enough interested parties to make the Russian state an unlikely culprit even if evidence of tampering should be discovered.
How many of those interested parties were actually identified as culprits in widespread hacking of election related systems in the 2016 election?
You say there was "hacking of election related systems"? What happened? Maybe I'm just out of the loop?
It doesn't seem to be in doubt there was a conspiracy, although it is probable that all of the consequences are not mentioned in this indictment. The indictment mentions other states, but focuses on Florida.

And that's where I wonder why at the outset of an investigation into whether voting-machines have been tampered with, the Russian state should be assumed to have done it.
You're certainly not alone in your doubts. Many people have assiduously been not assuming Russians had anything to do with tampering with the election every step of the way. Guccifer 2.0 was supposed to be a random Romanian hacker and yet it is now confirmed he was a member of the Russian military team attacking the US.
It's not helpful to dismiss stuff as a conspiracy theory these days in a general sort of way. The reason is that disbelieving one "conspiracy theory" requires you to believe in another, larger one. If you don't believe in the indictment, you are necessarily positing a massive conspiracy to frame Russia. There's no apparent simple, comforting explanation that doesn't involve large conspiracies.

Can you say more specifically where your link covers that, I didn't see it.
The lack of proof so far that votes were falsified is a separate issue, but given the existence of the conspiracy, it's unclear why one would rule it out.
