Probably because: \* SQL Server is proprietary \* SQL Server licenses are expens...

I chuckled a bit because the GP mentioned Oracle. I'm sure you've heard this one:

Customer: "How much does an Oracle database license cost?" Oracle Rep: "Well, how much do you have?"

That's actually not a joke. Oracle liked to argue you should accept server licences as being a fraction of your budget, so when it went up you'd automatically pay them more.

Amazon actually does allow SQL Server. The poster saying it probably didn't was influenced by the fact that Azure, Microsoft's own cloud solution is an AWS competitor.

To your own points:

SQL Server is as proprietary as Oracle SQL Server is cheaper than Oracle SQL Server is being ported to Linux in 2017 :)

Amazon.com seems to strongly encourage the companies it acquires to use aws. Apparently, woot.com is fixing to rewrite the website in Java or something just so they do not have to use Windows. Apparently, it makes sense to them.
