Seems to me it's just the present day version of going out into the highways and byways. Is it not?
Of course, some people really don't want "them" to come in.
The technique of broadcasting over cable, airwaves, internet, etc., seem morally neutral to me.
The message broadcast should be the subject of criticism, imho. If it's a milquetoast message, then zing it gladly and with fervor.
But if we're gonna complain about advertisements, why not just back up a few steps and complain about tv's and electricity???
