Hi James,
I hear you. CA's goal is not to make a profit on field-developed solutions, rather leverage the Ideation forum to not only post product enhancement suggestions for community comments / voting, but also enable people (including CA people) to share their related field-developed solution so that 1) other customers can benefit (and provide even better feedback on the idea) and 2) CA has a working prototype that it can use as a model to implement the enhancement into the product.
There's no expectation that CA would charge for incremental features that are adopted into the product. Regarding IP ownership (Rule #2), this is a protection for CA - so that we can incorporate features / improve the product without fear of being sued, at some point in the future, for theft of intellectual property.
By all means, if someone would like to create and sell Endevor add-on products, they are certainly welcome to do that. There is nothing in our Ideation/FDP-sharing proposal that precludes people from developing/selling add-on software products. There are companies that are doing that today.
Our goal of this proposal is to combine the Ideation process and our Agile development methodology so that CA can work with the community to incorporate and publish (and support) those product enhancements that are important to the Endevor community in a timely fashion..
Pete
