I don't know if this has been answered anywhere. I was just wondering why it was changed. I can guess it was because 'answer' sounds too definite and concrete while opinion is more loose and not so definite.. If you get what I'm trying to say.

Your guess is exactly it. What we're giving is nothing more than our opinion of what we would do, not necessarily the for sure answer that will be the solution.
Still, I preferred "answer" over "opinion." It sounded better.2
