It's not the IP, it's sadly how people react. Some folks will be appreciative of help, credit to them. Others will immediately get back how they tried it, it didn't work and now they need you to rewrite everything, or do their project for them, or redesign your product to match what they want it to be. And if you politely refuse, it quickly escalates to threats of trashing your business through every channel, and other things.

So, the safest thing to do is not give details at all, or "leak" them like another reply in this thread mentions.
