Where else would the CI service for a Microsoft product be invented? NIH is a weird insult in this context. If Microsoft had instead acquired a CI service you’d be complaining about how they’re reducing competition.

Microsoft had their own CI service and it existed before GitHub Actions did, it was renamed Azure Dev Ops but it existed before GitHub Actions and it was largely similar from what I remember.

FYI Azure has its own CI service and that's pretty bad too.
