The original people (not recruiters) who reached out to you should've connected after the decision was made. They probably figured the recruiters would do their dirty work, so no need to engage.
Full disclosure: I worked at Microsoft for over a decade, so I know how slow and lumbering it can be. I bet some emails were missed and people didn't follow up because "they had a lot of other things they were tracking".
Total misjudgment on their part. Thanks to this one HN post they already lost in terms of developer good will way more than his potential salary would be.
Every time anyone who uses WinGet, who read this, will think 'oh, yeah, that's the tool that Microsoft build their version of behind original author's back, while stringing him and ghosting for few months".
In reality, these kinds of antics just don't hurt companies significantly -- even ridiculously horrible things that are arguably crimes against humanity (have I invoked Godwin's law?) In comparison to some of the incredibly awful things companies do (and get away with), this is minor to the point of not even being a footnote in the annals of evil (note to self: don't google that term to check the spelling...).
However, there will be a few of us who will be reminded of why we don't do business with MS (and hence will have no need of WinGet). It won't make any difference, but it will be there.
I suspect a week from now, 99% of people who read this will have forgotten about it.
