Without knowing what the application is, obviously there's no way to comment on its use. Perhaps you don't specify because you're afraid it would get the thread locked? (Which I suppose is not unreasonable given the history here.)
As far as I know normal DOS applications, I mean the kind you are probably thinking of (i.e. excluding anything with networking or low-level disk access), don't use anything that games don't and should run in DOSBox. That is consistent with everything I've experienced myself and heard from those that have.
I am not sure what this exactly is supposed to mean:

If this is to say that we must never be angry at someone that did something for free, I have doubts at least. Taken strictly it would imply that writers of viruses and other malware are just fine because they don't charge for their 'product'. Even apart from actual malice such as that, a product may from one's own point of view have sufficient flaws to be worth less than the nothing paid for it. To ask exactly when people should be angry seems too philosophical at that point; it's sufficient to note that they will be in most cases even if they do not publicly express it.
