Red Hat: We're Working With Microsoft to Bring You Proprietary Software of Microsoft
THIS should probably come as no surprise. This crude marketing from Red Hat basically asks people who use a free distribution of GNU/Linux to start paying Red Hat in exchange for a relationship with Microsoft. They moreover use subtle FUD, insinuating you might have trouble with the software unless you pay Red Hat.
It should moreover be noted that Microsoft SQL Server does not properly run on GNU/Linux. It's some cheap imitation, leveraging Drawbridge. █
