A content provider or designer revoking the license on the work supplied to a client for non-payment?

I dont think i have ever seen this happen in the industry and yet, it is perfectly legal to do, especially if the said designer or content provider hasnt been paid in full for the work they did.

You would figure, rather than posting on various boards saying 'so-and-so owes me monies for their design/content' they would just email the company, tell them their license has been revoked, post that it has been revoked on the boards, then DMCA the company, host, billing provider, etc.

Im pretty sure that payment would be made REALLY quickly, in fact i would say it would get made 100 times quicker than it would by posting non-payment issues on the boards.

Your thoughts? Have you ever heard of this happening?
