Microsoft deprecating Oracle client in Dot Net 4

Microsoft has announced through a blog that the ADO.NET 4 spec will mark the Oracle client as deprecated with plans for removal. They are also recommending that users go to a third party Oracle provider. Stop Helping the Competition? Wow, this will mark the first time an ADO.NET provider has been removed from the .Net framework. Is this a case of Microsoft trimming the fat, or pushing Oracle? I always thought it a bit of a free ride that Microsoft was helping Oracle by building their provider for them...
