This contains a decent summary, including some laws:
https://www.eff.org/deeplinks/2023/05/10-years-after-snowden...I'd mention there are two big but abstract consequences.
1) The leaks significantly harmed international relationships and the result of this game much more ammunition to political adversaries like China and Russia. People argue that this is a consequence of Snowden's leak but that's like arguing that a mass shooting was only problematic because the news informed everyone. In a way yes, but it's not like those people would be alive if the news didn't report... It's not the real problem even if you wanted to argue over-sensationalism.
2) It seriously galvanized the battle for encryption and laid the pathway for the subsequent rapid rise in usage of tools like Signal and more funding and energy for building tools like Matrix and many others. Google's Project Zero certainly was influenced by this event.
While I get that these are more abstract, they are certainly consequences and certainly nothing to be scoffed at. This is another problem with the perception of consequences, is that often they are more subtle or abstract. But subtle or abstract doesn't mean any less impactful, just more difficult to trace. More opaque. We don't have a counterfactual to prove that these things wouldn't have happened without the leaks, but I'm certain the timing and degree would have been different. Do you think the world would be different had he not released them? I don't think this is an easy question to answer because it requires being exceptionally detailed and paying very close attention to a lot of events.
