I realize you asked sarcastically, but as of relatively recently WinGet is shipped by default with the latest versions of Windows 10 and in Windows 11. [1]
on both cases, not having a default package manager shipped caused zero adoption attrition, I mean, besides the attrition of needing a non-standard package to begin with.
IMHO it is though. I have a windows VM I rarely use and tried using a package manager at some point, but end up not succeeding until winget was part of the system and was a no-brainer.
It was only partially sarcastic (yeah that didn't communicate at all, bad habit on my end), I had googled them but didn't quite understand the winget situation at glance. Thanks for the answer, actually appreciated!
But why is being installed by default important?
