While the technical side of the news is interesting, the organisational repercussions worry me. Microsoft (who owns GitHub) is already one of the largest tech companies, and I would not be surprised if this move was intended to weaken NPM and Docker in an attempt to acquire them.

I fear a future where everything one requires to develop "socially" depends on a single super-entity. GitHub and VSCode were the first steps in that direction, and now package management. My guess would be for CI/CD to be next on their list, with more integration of Azure somehow (potentially under the hood).
