>>6310571 The Discord communications system requires running a nonfree client program that collects lots of data about users.
The developer denies the claim that Discord reports which processes are running on the user's machine.
Also, selling data is not the sole way that the company makes money, but I don't think that question directly matters anyway. What matters, ethically, is what the software does to users. The developers' motives for making it do those things are pertinent to understanding the situation but they should not alter our moral judgment of the program.
I would appreciate suggestions of other pages to use as references for specific ethical flaws of Discord.
