This feeling has grown on me to the point i've began avoiding using most free software besides some i can't live without, and to these projects i donated the amount i could as a student from a developing country (in case you're curious, i donated $2 to Mozilla, Wikipedia, Sumatra PDF, Tab Session Manager, Cookie AutoDelete and Calibre; as i use these software everyday).
Still, i feel bad as the "free software contract" is not clear as in paid software: am i donating enough or am i just reaping the hard work off a stranger all the way around the globe?
This is an uncomfortable position, as I don't like the feeling of stealing the hard work off of anyone and don't want to put myself in that position either.
So, how do you guys cope with these feelings?
