A While back Ian Cooper blogged about the need for active development of LINQ To SQL, he had this to say
As a community, as people begin to realize the suprising power of LINQ to SQL, I would like to see us dispel many of the myths that seem to have grown up around that product. I would like to see us put pressure on the Data Platform team to provide the support for LINQ to SQL that we want going forward. Community reaction is everything and if the LINQ to SQL community remains silent in the face of the more vocal, but probably less numerous, EF community, we won’t get the product we deserve
David Hayden has made a call to Microsoft to Open Source the development of LINQ to SQL in response to the ADO.NET Teams announcement on the future of the Entity Framework and its 
forgotten other LINQ To SQL.
The ADO.net team says that they will improve LINQ to SQL based on community feedback then there is please head what David Hayden and Ian Cooper are saying.
Simon Segal has previously made a Save LINQ to SQL badge which apart from bring really cool is apt.
So if you want to keep POCO objects free of the IPOCO interface (at least in V1 of EF), I would ask the Data Dudes to set LINQ To SQL Free as per David Hayden’s Suggestion.
