These are non-issues. The idea is not "share all data". If we copy the GPL model, all you need to share is the source code to any program you distribute in an uneditable form, and then only when someone asks for it (at which point you may charge a reasonable processing fee for the trouble). It's really not that onerous. No one is making you share your private software.

For "software" replace "food" and for "source code" replace "ingredients". You can cook whatever you want at home, but when you start selling food to people certain responsibilities kick in. If a kid is selling lemonade but is too embarrassed to tell you what's in it, would you drink it?
