I guess the responsibility is on the user to dig through the FAQ or privacy policy to discover they use Bing and then read between the lines?

It’s disingenuous and misleading to the average user. They should be criticized for it.

I absolutely agree that they should be criticized for it, or at least explain their deal with Bing. If one can trust Google not to create ad profiles from Google Analytics data, one can also trust Bing to not use ecosia data to build user profiles. But for that to be a trust decision, we'd need to know whether they actually have any such deal with Bing.
