Who can hate me next?

I'm trying to think who might hate who next, and then consider what it would take to be the hated one. Nice huh?

Encyclopedia salesmen hate wikipedia...
And CNET hates Google
And newspapers hate Craigslist
And music labels hate Napster
And used bookstores hate Amazon
And so do independent bookstores.

Dating services hate Plenty of Fish
And monks hate Gutenberg
And courier services hate fax machines
And the local shoe store hates Zappos

Thanks to Seth for the short hatred list.
