It probably cost them a little, but not a huge amount. It actually is a smart deal for BB too. Who is BB's big competitor right now? It's not MS. It's Google. Why give Google revenue when Bing is, by most measures, just as good? So MS comes to BB and says, "You really need to be fighting this front against Google. They're eating up your mobile sales. Bing is a great way to fight against them. Your customers will have an experience that's just as good, although admittedly some will be unhappy with the brand. And sure WP7 might be competition in the future. But frankly, its a longshot, and you have your lunch being eaten today. And lastly, do you want Google to screw you over in services in the future if it came to that? With both MS and Google battling it out, you'll always find one provider that will give you a fair deal."
