Google has always been good about helping users leave them.
In fact, they make it really easy to leave. You can literally pack up your virtual Google bags and port yourself to different web services anytime.
Google Takeout is a tool to help with just that. Takeout is a service from Google that will give you an archive of all of your Google data from just about every service Google offers. All you have to do is hit one button, and Google starts putting it all together for you.
You can check it out here:
You can either have it do everything, or you can manually select the services that you want archives of. Services include your +1′s, Google+ Circles, Google + Streams, 3D Warehouse, Blogger, Buzz, Contacts, Drive, Latitude, Pages, Picasa Web Albums, your Google Profile, Reader, Voice and Youtube.
So, whether you’re actually packing your bags and leaving Google (I know I won’t be anytime soon!), or just keeping backups for the coming web apocalypse, just know that Google is ready to help you leave anytime you want. Don’t ever say they made it hard!
