An article full of nonsense. Discontinuing Google Reader IS NOT sending a message to enterprises that they should not use Google product for the long term.
Sorry, but your statement needs more to back it up, because the opposing viewpoint has an easy logical justification. Why should companies transfer their core infrastructure onto Google's products if they know Google might decide one day to discontinue them?
I know lots of companies rely on and pay for GMail, I'm sure it won't be discontinued anytime soon, but I'm also sure this event puts thoughts in the back of many people's minds about that eventuality.
The day that e-mail becomes widely irrelevant is the day that Google thoughtfully cancels Gmail. Google is a business. If they lose enough customers, it's not worth maintaining an expensive system just to satisfy the vocal minority who gets up and writes self-entitled articles like OP's. Google has been pulling plugs on services for the longest time; they're not a charity, they're a company. I don't think this makes them evil!
Companies don't run their infrastructure off Google Reader! How can you compare this to gmail? Google makes money off gmail (Companies pay for Google apps) - not Google Reader...
