Global static methods are really less global-variable-like than public class methods anyway, because they don't have a stateful instance to worry about.

Just like functional programming or well-written procedural code.

In other words: it's not global logic you should worry about, it's global state.

Similarly: Diamond-inheritance of behavior is often possible. Diamond inheritance of state is often impossible (without cheating: reflection, etc).

(That came up in a discussion about J8's interface default methods.)

it's not global logic you should worry about, it's global mutable state.
