I'm talking about licensing support, not tech support; and more specifically licensing support of a service rather than a product.
Microsoft don't charge you to talk to a person when you have issues activating windows (and I've never had one of their products break when I changed region). I've never had to deal with any of their services breaking for me (only products) so I'm not sure whether they try to sell you a support subscription when you use eg http://support.xbox.com/en-GB/contact-us?isChatCallAvailable... , but I'd expect it to be free if it fell into the category of "stuff I purchased that you failed to deliver to me".
