Yes, but the dir/ls alias behaves nothing like it's counterparts, so it's actually confusing when you use dir or ls but none of the familiar usage works.

Just wanted to add my two cents here that I normally use `ls` on PowerShell (instead of `dir` or `get-childitem` or `gci`) because it seems expedient. (I come from a Unix background.)

Yes, it does confuse me that plain `ls` in PowerShell is more like `ls -l` on Unix, and this confusion sometimes causes me to type `ll` (my normal Unix alias for `ls -l`). But still, I prefer `ls` over `dir` in PowerShell.

So I guess I'm saying that I'm fine with some of the aliases. (But `curl` and `wget` should be removed, yes.)

Hypothesis: The Windows world is a closed ecosystem. The developers and most of the users aren't familiar with any of the non-Windows systems. They were given a list of commands to map to the closest Powershell equivalent and made aliases for the basic functionality.

That is the only explanation I can see for why the would pick those commands.
