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".
So much of what Microsoft has been doing — GitHub, .NET Core, NPM, Visual Studio Code, Windows Subsystem for Linux, etc. — has been to build goodwill with “developers! developers! developers!” Taking the resources to do an acquihire (or hire + bonus) right is small relative to the PR hit.
And when I first heard about WinGet I though, "Yay! They continue to catch up to the place where developers are! Good for them!", but then this surfaced.
