Open Source or Proprietary?

considerations

Take into consideration the following:

  1. Do I really want to pay royalties and/or licensing fees for a product that I cannot be entirely sure of what it consists of? (Similiar to buying food without knowing the ingredients)
  2. Have I the time to deal with learning proprietary standards based on commercialized OSes, APIs, etc.?
  3. With consideration of the previous two questions, am I capable and competent to handle the responsibilities of maintaining a system based on open standards, that is free, but comes with no guarantees?
