I never used the word "stupid" and I don't equate not knowing about IP ports
and firewalls to stupidity.

And with the current scheme, I don't need to know either.

If you suspend or disconnect from the network, sharing is disabled. If you
connect to another network, sharing is disabled (unless it was previously
enabled, by the user). It's also possible to disable sharing for networks you're
not connected to.
