That's the crux of my problem with facebook and google: companies making billions by freely using their users OC. For Reddit it is kind of okay because they are not yet building selfdriving spy, or selfSpying VR.
except of course that a) they told their users and b) they provide an excellent service for free so getting mad at them for needing to profit is more or less the same as getting mad at yourself for wanting reddit to still exist in five years
edit: tag reddit please
