Is it really though? Bing has been consistently worse than Google over the years. Maybe our definition of vendor lock-in needs to change.
Honestly at this point it doesn't even matter how good Bing is - we've been unconsciously trained to work with Google's algorithm in particular and they just have a de facto monopoly on the mental process a person goes through to formulate a search. Everyone's workflow everywhere will be worse and take more time if they voluntarily stop using Google, that's not what I consider a fair competitive landscape.
