Just installed GoogleChrome on a Mac, suddenly 4 other Google apps are installed

I just installed Google Chrome on my Mac and suddenly Google Drive, YouTube, Gmail, and Google Search apps are installed automatically it seems..

Can Google actually do that? Install a ton of unrelated apps without my permission? Or maybe, such a clause is now being snuck into the ToS?

UPDATE: Even worse, as I just discovered, they can't be deleted from the Launchpad! Neither do they show up in the Applications directory! WTF! How do I get rid of the damned things??
