Walmart has sent a DMCA notice to TechCrunch and SearchAllDeals.com, a shopping search engine and deals aggregator. (Think of it as the Techmeme for deals on the web, with a Google custom search engine to boot.)
Both sites posted some information about "Black Friday" sales for discount giant Wal-mart. But Wal-mart is claiming copyright infringement. It's also saying the info wasn't supposed to be out before November 24th.
The problem is SearchAllDeals doesn't host content. It simply links to it. This amounts to free advertising for Wal-mart.
And since TechCrunch also has the info, then Wal-mart has a leak problem, which is neither TechCrunch or SearchAllDeal's problem.
If I were a competitor such as Target or K-mart, I'd be stepping up to the plate and making the most of this "controversy" by freely offering up my own deals.
