From <http://arstechnica.com/information-technology/2016/03/sql-server-for-linux-coming-in-mid-2017/>: The announcement implies [one of] two things. Either there is a large number of Linux-using corporations out there that are desperate for SQL Server's feature set (as opposed to open source databases such as PostgreSQL, MySQL, or MaxDB, or the proprietary ones such as IBM's DB2 and, of course, Oracle's Oracle), or there is a large number of SQL Server-using organizations out there that are keen to ditch the cost of their Windows licenses but happy to continue to pay for their SQL Server licenses. Neither seems obvious to us. Nor to me...
