Try coming home and finding your house empty (!) and wife and kids gone to another country. Now that's deception. I know a few people who enjoyed this experience.
"If you're tied into the $Service world-view" any business that takes a conscious business decision like that needs to carefully look at the benefits vs the risk.
What about Google ?
Q: Have they ever closed a paying service ?
Q: If so, have they done it in a way that would make you lose your data ? Or put you in a situation where you had no alternative in reasonable time ?
I have used online paid services that have stopped working, without notification, even after the closure, kept billing me, without providing support.
I have paid solutions sometimes several 1000 $ without getting a single support answer when encountering problems.
I don't mind using a service if
* it has alternatives
* I can easily extract the data
A service is like any job or relationship. It can end at any moment. The way it ends is as important as the way it operates. I trust Google on at least ending their services properly. From my knowledge they have a good track record. Google Reader is a good example. Free, 3.5 months notice, open data, several alternatives available. I really don't understand why people complain.
