Re: Beware online "filter bubbles"
"Issue" may be too strong a word; "fact of life" is what I'd call it. Google isn't some kind of public agency founded on altruistic principles to serve the public, and is under no obligation to even attempt to present content free of bias. It's helpful to know what their methodology is, but they're not obligated to disclose it. Like many another "free to the public" services (for example, Aikiweb), someone's paying the fiddler and that someone gets to call the tune.
