Did you even read the article? The guy never claimed some elite stance. Google is well-known for its internal tools. It would help to educate yourself a bit.
If you read between the lines, the article sounds a lot like "I know better", implicitly "because I worked at Google" (as per the "ex-Googler" qualifier in the title).
Consider this:
> Introducing code search and monitoring doesn't require asking anyone on the team to change existing workflows. Changing the code review tool, however, does.
It basically sounds like the author wants to take over and tell everyone how to do things.
After time at Google, comparing them to other organizations all the way from 8-person start-ups to other FAANG+Microsoft, there are a LOT of downsides to their tools and their isolated ecosystem. A lot of things are more difficult and take longer to just get done than elsewhere at the same quality.

This may also be exactly the attitude OP was talking about.
