shared source

Is Microsoft joining "Open Source"? That still sounds alarmingly suspicious indeed, but.. let's see..

Tectonic writes: "Bill Hilf, general manager of platform strategy at Microsoft, announced last week at the O'Reilly Open Source Convention (OSCON), that the company was submitting its shared licences, which include the permissive license, community license and reference licence, to the Open Source Initiative (OSI) for certification as true open source licences."

So, "Shared Source" licenses, previously known as *not* adhering to the Open Source definition and for that matter the Free Software definition are submitted for approval as such. Weren't these a "see but don't touch" kind of licenses?
