Unless you're viewing it from a purely financial lens (e.g. you're closely following the MSFT stock), it seems like "joining GitHub" is probably closer to reality than "joining Microsoft" for most purposes. I don't have any more information than the post has, but it sounds like:

* The Spectrum product will be merging with the GitHub product in some sense, maybe integrating completely, maybe re-branded with GitHub branding, maybe separate branding but tighter integrations. It certainly doesn't seem like it'll be a separate Microsoft-branded product.

* The Spectrum team (three people) will join the GitHub team, which of course has its own office, culture, vision, etc. Maybe they'll keep working on Spectrum, maybe they'll work on other parts of GitHub, maybe current GitHub folks will join them, but point is, the people they'll work with are the people who work on GitHub, not Microsoft as a whole. It certainly seems unlikely that they're moving to Redmond to work at Microsoft HQ.
