From the side-lines it looks like they're slowly becoming an unstoppable dominant force, what's surprising to me is AWS's / GCP's inaction, they're either asleep at the wheel or they don't see Microsoft's dev mindshare grab as a threat.
But I do wonder if AWS will try to buy gitlab.
Maybe when Microsoft would have opened up some years earlier, Codeplex would not share the fate of Google Cloud.
When did Amazon give up?
