Believe it or not, there's a whole host of laws around and against foreign involvement in American elections, going back basically forever. Comparing Boeing and Russia is pretty ludicrous.
I am curious what these laws are, and what constitutes involvement. Am I allowed to comment on American elections even if I am not American?
A lot of people here are talking about interference, which sounds like a very nefarious thing. But in reality, what they mean by 'interference' is just posting on the internet about why one candidate (let's be real, probably Trump) is better.
The two big categories in my mind are foreign campaign contributions (usually misdirected through others, so sometimes also fall out as fraud and money laundering charges) and failure to register as a foreign agent.
As a reminder, both of these categories have seen grand jury charges and subsequent guilty pleas by Trump associates. These have often paired nicely with 'lying to prosecutors' charges, which help clarify that they knew they were up to no good...
