There is a slight difference about being "independent" than "autonomous", there are a lot of dependencies and that's where cooperation takes place. Not only you have to adopt the protocols,  but also some best practices about how you use them, which drives interoperability.

Yes and no, in some cases you may have agreements that as an operator makes you carry prefixes that do not belong to you (transit is a clear example) and here is where some fat fingers screwed up and continue to screw up, announcing (some times intentionally) wrong prefixes that get propagated to some portion of the overall network table through operators with lax routing policies and management.

There is currently a lack of good/strong authentication for accepting routing announcements as valid with a trusted origin when they might not be, for whatever reason, once again some times intentionally.

Actually is not very hard to exploit this weakness in the current routing architecture and protocols to force prefix hijacking, hence traffic diversion.
