"All of Google's products are complementary products that create lock-in"

I disagree. Chrome was created to be a standards based browser, Android to unify the different phone operating systems circa 2004. I picked Google products because they allowed me to get out if I needed to. Gmail provides IMAP, POP. Docs and Music let you take out your data as needed. Google intentionally creates a way to get your data out. All of these things require foresight and work to pull off.

Does the lock-in exist because no one else is offering the same service? Potentially. But the intention of the company when they created these services was to create the best service, not a lock-in service.
