The actual harm is that other companies can't use that additional access. If they could they might be offering better products than Google to me and you. You might not care about better products, but I (and probably many people on this post) do.
Except allowing other companies to have that access results in a huge loss of security. I trust google enough to install their browser, they already do what they want with my computer, I don't really want to evaluate whether or not I trust every other random website to have that access or trust that they'll continue to be trustworthy at some random point in the future.
