They're talking about changing it on the Windows version of Powershell too; I don't think it's something to be "ashamed" of, I thought it was a huge convenience - I knew that wget wasn't literally wget, but when I needed to fetch a webpage I knew the command to use without looking up Invoke-WebRequest or whatever it is and without having to go out and download the real wget.

I think taking the alias out is actually disappointing and a very slight change for the worse on Windows.
