For some reason I just get the feeling that the relationship between
*BSD and Linux is lacking in communication. Or that the timing is
wrong. The OS:es don't hate each other but they don't really understand
each other either.

So whenever some shared asset needs management there is a
statement like "if you really love me, you should involve me more",
from either side.

And yes, it is the common human mistake of simply assuming
everyone else in the world works exactly like me (and in worst case
we assume others are plain stupid or a lesser imperfect version of
ourselves if they don't). But as always, they are usually just thinking
differently, smart in another way.

So I think these communities need some relationship therapy.

Yours,
