EDIT: Sorry, this is incorrect. GH did ship them prior to the MS acquisition. I do however remember them taking an EXTREMELY long time to ship emoji reactions, which struck me as a fairly trivial feature. I stand by the point that GH ships features faster post-acquisition, though.

I remembered that reactions irked me for some reason, but I had incorrectly tied it to the MS acquisition. The real issue was this: it took Github an extremely long amount of time to add a feature as simple as reactions. Github was founded in '08, and didn't add reactions for another eight years! But I distinctly remember once MS acquired them, they started shipping features left and right, and features much larger than simple emoji reactions.
I think GitHub actions are pretty successful, which may not have been developed by Microsoft as it was launched right after acquisition, but I guess it's easier to keep free since it runs on their own hardware.
I don't immediately see copilot as a GitHub feature, but maybe that'll change for better or worse.
Under MS, they shipped - just off the top of my head:
* dev containers
* vscode-github-in-the-browser
* github actions
* that extremely useful fuzzy-find that repos have (press t in any repo)
* copilot
I seriously doubt they could have shipped a single one of those things pre-MS.
They shipped that in 2011[1]

I didn't know this. Thanks for the tip!
My best guess, with no knowledge of what actually happened, is that it was derived from Azure Pipelines.
On the other hand, what they didn't have was search locked behind a login screen.
I have never, ever in my professional life thought “I need an emoji for this”
And GitHub actions were basically sharing the infra of Azure Pipelines.
