Well then, it is safe that you did not get offended by anything I said then, as I have not by your words. I still think we disagree on a significant point here, free or paid. If something is free, to me, then that is what it is, free of all things. If paid for than it becomes the purchaser's responsibility to do their leg work, just as you have, to prevent from having buyer's remorse. Not that it can always be avoided but at least it can be a minimum if checked correctly. In fairness you are only trying to get word out to prevent anyone from making such a mistake and for that, you are righteous in your doings, so I will leave it at that. You prevent someone from paying out or even a developer learns from what you have to say, since these are the two most critical reasons for leaving feedback after all.
