I think something like this also depends a lot on your culture and how you view gift-giving/ sharing.
As a westerner, I personally see sharing between myself and close family as a way to allow my "family unit" to "get ahead" in the world. If we share between us, that will save us money in the long run for other things (5 apps =one gallon of gas = two days of travel to work = $144 income)
However, I would not share with my friends. I might let them play the app on my phone, just as I might share a passage of a book with them or let them watch a movie with me at my house, but I would NOT give it to them.
I have to work for my money, so why should they get free things? No one gives ME free things.
On the other hand, someone in another culture might view it differently. They might for instance think "Oh, why should I make that person I care about suffer when I can provide them with something I already have?" akin to sharing food, or in as a less dire example candy or sweets. Or to a further extent some cultures would EXPECT you to share, and would see it as disrespectful if you didn't.
To me, something like that would be similar to buying a movie ticket, but letting your friend in the back door.
Culture has a lot to do with how we form our values and views on ethics, morality and how we interact with other people so I think it's unfair to assume that everyone has the same core values and view of the world.
So, it depends on how you view
your morals and where
you personally stand on the matter. If you think it’s fine, it's fine. If you feel guilty, or shameful or backhanded about it, then it probably is.In my eyes, if you have to ask US if it's wrong, you most likely think it IS wrong and just want comfort or reassurance that you're not doing something "bad"
