So you think Microsoft’s real answer which should be read into their statement is:
“Microsoft is using our own rendering engine out of a sense of duty to web browser diversity, because we don’t want the web to suffer the problems of monoculture.”
I'd phrase it slightly differently, if you want a one sentence response. Which is "Standards are important and we believe that multiple browsers and rendering engines are necessary for improved standards compliance across the board."
“Microsoft is using our own rendering engine out of a sense of duty to web browser diversity, because we don’t want the web to suffer the problems of monoculture.”
Is that right?
