Re: MS spreading more poison
Microsoft, like every other BigCorp is not anti anything they are simply pro money. They make money from Linux VMs running in their cloud so they want to support it.
Under Ballmer they saw Linux as a threat to Windows sales so made life hard. Things are different now.
The desktop (and to some extent, the server) OS wars have come and gone. MS are looking at a different future where you pay them to run your VMs on their tin and they don't give a shit what OS is running on them.
Same with SQL server. Whether you run it on Windows or Linux you still give them money for the licenses.
You appear to be under the mistaken belief that MS do things for ideological reasons. They don't, they just want your money.
