Some things I have been thinking about are centralization risks, channel state privacy, false positives. A false positive occurs when a watchtower incorrectly identifies a regular, honest transaction as an attempt at fraud.

Idealy you run your own watchtower on another server than your LN-node in a different network. Then you don't have any of those problem you mentioned. In my opinion a false positive can only happen through a software bug which will be fixed if discovered.
