the effect is the same as intentional scraping and outright stealing

The google engineers intentionally sent this click data to Bing, so is Bing really stealing? It's odd to act surprised when Bing uses the data that was intentionally sent to it. Bing could specifically ignore Google search results pages when it is tracking clicks, but is that legitimate? Google scrapes everything, why shouldn't Bing?

They were testing to see if it was true. Many users are doing it, bing is taking data for non-google engineers too.

The point of collecting click data is not to target google engineers, it is to collect data from masses of people doing regular searches and to improve them by seeing which links get clicked on, so obviously Bing is "taking data for non-google engineers". Furthermore, there's no indication that google search results pages are even distinguished from other pages in this.

In fact, the data that it takes from Google engineers for carefully engineered corner-case searches is the exception.
