There are lots of good examples of adoption despite non invention.

Ironically, Typescript is not the best one. I can go into great detail - i was overseeing production programming languages at Google at the time, but getting to Typescript (which was the right choice) took a lot.

For most things, even things that seem to be contentious in the broader developer world, internal developer infrastructure teams were often relatively agnostic on choice as long as we had the resources to do it right (IE deal with migrations, etc). You'd have to push people to be meaningfully objective in evaluations, but once they realized you were not going to let them get away with nonsense, you got reasonable evaluations and options. Not always (can't avoid zealots at this scale), but a lot of the time.

But Typescript vs Dart vs Closure (GWT and a few other things were in there somewhere, too) was just particularly contentious for $reasons.
