So essentially it took until 2009 for Microsoft to even begin to admit that RPC, a few rather crappy scripting host options and RDP were inadequate, but it took them over six more years to finally implement what is pretty much the gold standard of encrypted TTY interfaces.
No, they have never stated that their previous technology was inadequate. They are just providing yet another option to their existing solutions. That you think that SSH is the one-and-only answer shows your biases rather than demonstrates any admissions of inadequacy by Microsoft.
Maybe this is part of the turning over a new leaf, but I can't help but imagine that the next version of Microsoft's coursework will announce how innovative all of this...
There is no way that they will attempt to claim that they invented SSH. Apart from being so easy to disprove (and thus ridicule), it would also go against the current Microsoft policy of working with standards.
...much as it went around declaring how innovative Powershell was, when all it really is is an overly complicated descendant of Bash, inelegant, overly verbose and unnecessarily convoluted.
Once again you have let your hatred and obvious lack of knowledge get the better of you. The basis of Powershell is that it treats everything as an object and is integrated with
I just hope all the Redmondites see the irony of MS sitting around for two decades declaring NT's superiority because, you know, Windows and all, and now essentially reinventing, badly in many cases, what the Unix ecosystem has had for decades.
For someone who thought that the only remote access that Windows had was telnet and that Powershell was a copy of something that it is almost completely unlike, I think that you need some more education before you can lecture anyone about the shortcomings of Windows.
