In my opinion I'd rather prefer Google not linking to a website. Bitcoin doesn't have an official website in the first place. Though this would be a special case, as it's not like Google is manually adding these information. They're automatically added by their algorithms in the first place.

Bitcoin is a rare case whereas a platform actually has no owner and official website, and obviously the Google algorithm doesn't know that. Repairing problems such as this would probably require manual alterations by a Google employee.
