Yes, the fairly obvious limit of going somewhere the US doesn't have an extradition treaty with. In Snowden's case: Russia. Which I personally wouldn't be thrilled to do, but the options are limited.
Lots of misrepresentation going on here. An extradition treaty merely facilitates things. You can have protections despite a treaty (e.g. France for its own citizens, ever!) and you could still be extradited if there isn’t one (there just isn’t an agreed upon mechanism for how to do it).
Yeah I think that's a pretty common thing to do. Outside of US and some EU countries, I know Carlos Ghosn is famously hiding in Lebanon where he is a citizen.
You’re right, every treaty is a different beast and there are no absolutes. But the general principle is Further, 18 U.S.C. 3181 and 3184 permit the United States to extradite, without regard to the existence of a treaty, persons (other than citizens, nationals or permanent residents of the United States), who have committed crimes of violence against nationals of the United States in foreign countries.
If the applicable treaty or convention does not obligate the United States to extradite its citizens to a foreign country, the Secretary of State may, nevertheless, order the surrender to that country of a United States citizen whose extradition has been requested by that country if the other requirements of that treaty or convention are met.
Those seem to be the mechanisms to extradite in the absence of a treaty. No point in having laws about treaties because ratified treaties trump the law (is my understanding).
Go to Russia and have a use for the authorities there, or have a lever/debt of gratitude.
I genuinely don't know where Snowden sits on that - I think he serves as a useful demonstration of the power of Russia and the failings of the US, but obviously know nothing.
On the other hand, a failed crypto bro who has taken oligarch money and can't repay it with interest. I think that is going to be the very definition of a "Russian Holiday".

It's not hard, in theory, but it does rather limit your movements going forward.
