I dunno... all of this sounds like fearmongering and some of these things are perfectly analogous to the way stuff already works.

For example: "Want to continue using SuperAwesomeApp? Too bad..." Want to continue using TwitPic? Too bad. Obsolescence happens, companies shut down, products go off the market and cease to be supported every day. This isn't new. If there's enough demand for an alternative, it will happen. Where there's a market, there will be product.

Or: "It's either pay up or lose access." When I stop paying my gym membership I loose access. Nobody complains that "it's either pay up or get fat." Photoshop used to be a product, now its a service. This isn't an "injustice" it's normal business.

Data safety in the cloud though is a reasonable concern. You don't know what's going on with your data on remote servers. But then, most people don't know what's going on with their data on their own machines. We've found ways to implement safety and security on our local machines (monitor for malware etc...), I imagine we will eventually find ways to ensure it on remote machines as well. Maybe.
