Strategically it may be that Mozilla should have done that years ago, when Firefox had substantial market share and therefore a lot of effect on the user population. By accepting the Google cheque, they directed people towards Google and may have indirectly funded Chrome and monoculture. If they had directed people towards Bing when they had 30% market share, that may have resulted in a search engine duopoly instead, and a greater chance of Microsoft selecting and funding Gecko/Servo instead of Blink.
