There is really nothing to talk about. All cryptocurrencies, not just Hive, is subject to the same exact situation. A node operator in all cryptocurrencies can easily mess with the data they're relaying and it would be up to the scripts or the person to figure out if it's right or not.
All users can decide on which node they'd like to use, for whatever reason. Be it speed (low latency, better hardware etc. overall faster experience) or trust (they are certain that the node operator is not doing funky stuff in the background to their data)
