But there we are again - changing the terms of the discussion, your problem with it now is merely that you're complaining it isn't open source (hint: it's in preview still), and that it has incomplete Linux support.
Yet here is your original post where you apparently didn't make a sweeping comment and where you claim you merely asked a question:
"You've been able to use Python for a while in Postgres [postgresql.org], MySQL [mysqltutorial.org], SQLite [python.org], and even DB2 [ibm.com].
I can't quite figure out why anybody would want to use Microsoft SQL Server."
Want to retract that now? It's pretty clear you're backpedalling - I don't care if you want to ignore me, just don't pretend you're here to learn when you're clearly not interested in that, and just end up backpedalling when you get called out. People like me are more than happy to share our experience with such products, but don't waste our time if you're not willing to listen and are actually just busy being a zealot whilst pretending otherwise.
