Here's what you can do to change the trend:

When you make a technology purchase, you have a specific use in mind for that product. (Now, isn’t THAT a cosmic concept?) Unfortunately, that use is not relevant to the current standards in license or agreement process. Unless you intentionally include a clause specifically defining the functionality you expect to receive; as well as defining the process for testing & accepting/denying the product suitability; and clearly describing your rights to refund of all costs – you are purchasing the equivalent of vaporware.
