Sorry to see that Google is going the sleazy route that Microsoft and Apple have ploughed before, namely trying to hoodwink and browbeat users into installing and automatically updating software they don’t want via an installer.
Try to download Google Earth now, for example, and you’ll be directed to the Google Updater, which will try to persuade you to install software you didn’t ask for. (A great write-up of all this is at the Google Operating System blog.)
On top of the inconvenience and sleaze of all this, I was irritated to find that the Updater doesn’t actually work: Not only that, but the help pages don’t help, and there’s no direct link to the original files so you can download them separately. (Fortunately the blog above does.)
All in all, a sure sign that Google is entering the software business, since it’s adopting the same bait-and-switch, install-by-stealth tactics of its Apple and Microsoft competitors. Shame on you, Google.
