Because the focus is on Google vs. Bing, not Google vs. Bing's users or Google's users vs. Bing or users vs. users. >how is Microsoft's alleged behavior harming the user? It's not harming Bing's users to provide Google's results. What's in it for Google to help Bing's users? It's not as if Google is an NPO humanitarian effort to help people find the information they seek. >If Google's unique sales proposition has become, "we find obscure misspelled words better than those copycats at Microsoft" Obscure misspelled words are just one thing that Bing is able to get better results on thanks to this. They also benefit from every other kind of query that a user can make on Google.
