Well I think google.com/chrome isn't that hard to remeber, and besides, the value is the official website and not a redirect

Both are official because both are owned by Google. Besides, as a Wikipedian, I hold little value for being official. "chrome.com" is shorter and that's all the value I see.
You made your point, though google.com/chrome is more commonly advertised as google chrome's main website (in search engines results, google chrome's blog, etc) chrome.com does also get you there eventually but can it be considered as google chrome's website ?
Many years ago, I had this very same discussion with someone who contended that web addresses without www have less value than those with www because www is the client name in an FQDN. Nowadays, nobody even types www anymore.
Also what construes a website is nowadays more a matter of contents and the maintenance teams. Sometimes, different websites are kept under the same domain name and sometimes, the same website spans several domain names.
