Privacy and encryption schemes operating over the Internet already assume hostile actors can see your traffic at any or all points between your device and the other end, so that's not an added concern (and yes, lots of entities are snooping on every single thing they can, to be clear). Beyond that, it's just public protocols. Any holes or inadequacies in those that allow monitoring or eavesdropping are well-known and are why privacy and encryption schemes for Internet-enabled software exist in the first place. All that really remains is that one or more governments have secretly broken essentially all crypto. Which is possible, I guess, but unrelated to their developing the Internet. There's a non-zero chance there are shenanigans going on with some root cert servers for SSL encryption, which require trust for their related identity-assurance schemes to work properly, but again, that's not related to government development of the Internet.
