"The reason it worked with bing is that nobody in their right mind uses bing."
I'm more worried they compared a search engine running on servers fully under their control, and with a limited end-user interface, with a single use-case, with an OS running on users system and needing to support many thousands applications, and very different use cases. The way they break drivers looks to show they don't understand the difference. Once, they went even too far to ensure backward compatibility with admittedly badly written code - but too widespread or important to kill it.
Without also not understanding why Google still rules - and why so few people use Bing. Also, that Amazon ad always on top, is really useful? You can look for "corpse" and find on top "look for discounted corpses on Amazon!!!" or something alike. Maybe a good tester would have spotted a better context awareness would have been helpful?
