Some of us thought that the magic of these people would be imbued in the dev tools that they created, so if enterprises adopted the tools, then they'd reap the benefits of that same magic too. But this simply wasn't true. The tools didn't actually matter; it was the way they used them.
For example, when other companies started adopting tools like Bazel (open source Blaze) they wanted features like being able to launch ./configure scripts inside Bazel, which totally violates the whole point of Bazel, and never would have been allowed or even considered inside Google. The Bazel team was more than happy to oblige, and the users ended up with the worst of all worlds.
