I don’t see how this could be positive for any Software developer in the long run. I totally see how this could be positive for CEO/CTO, Project Managers, in the long run, and I see a few short term advantages for Software developers.

Let’s be clear, I saw that coming since Microsoft bought Github, and I am scared by the direction this is taking. The end goal is to move more and more control and power to non-software people about Software development.

By forcing every developer to not use their own tools this will have a lot of advantage for CEO/CTOs but this is terrible for software developers:

1. telemetry: they will try to find a formula to assess who are the best performer in a team. And as with SEO, any formula could be gamed, the best at this game, will not be the best software developers, but the one that will learn how to cheat.
2. global team tooling enforcement: vim vs emacs etc… ? Forget about it, the only way to work on a project will be via this unique allowed editor.
3. assets protection: impossible to download the code on your local computer to use external tools on it. The only way to have analysis tools will be via these “allowed” analysis tools. This will make code analysis and experimentation a lot more difficult.
4. Locked by promoting vendor-specific applications. As you will focus to make your code/app/product work only for Google Cloud for example, you will naturally use Google-Cloud-only features that will make your code difficult (or impossible) to move to another Cloud provider, or god-forbid, host your product on a non-cloud or private made cloud.

And I can think of other possible drawbacks but my comment is already long enough.
