We better be careful, with Googles track record they will be getting rid of YouTube soon and rolling it into whatever they are calling their Skype clone nowadays.
I think that five products are reasonably safe from Google's euthanasia project:
YouTube
Google Search
Chrome
"core" Android system + Play Store (it counts as one)
AdSense
The common factor between them is advertisement: vulturing on your personal info (Chrome, GS, Android), serving you ads (YT, GS), ensuring that advertisers must pay the vassal tax to advertise (AdSense), and walling you in ways that you can't fight back (Chrome, Android+Play Store).
Google stopped being a technology business a long time ago; pragmatically nowadays it's simply an advertisement company that dabbles on tech.
