Whoever wrote this piece forgot that Google has shutdown more Webservices than apple has ever created. Most of Google's webservices remained Beta for years and years (Gmail!!) Does these mean Google is getting bad at creating web services?
I think the "beta" label is used by Google and others as some kind of get out of jail card. Or rather stay out of jail.
If anything huge goes wrong they can always claim it's beta and not intended for serious use. With a beta label they can do what they want.
That, my fiend, is called "iteration".
Also, contrary to Apple closing Ping at full loss, when Google closed e.g. Wave, they recycled huge chucks of it, in Android text input, Google Translate, G+, etc.
