F95 is just a bunch of degenerates embracing what they are really. Its a good forum for the content it provides for sure, but yeah, in my time there I've definitely realized there is plenty of entitled people who think that just because something exists online, they're entitled to getting it for free.
Obviously I don't think people should really get up and arms over a pirating forum having users who, well, pirate, but at the same time, yeah that's a pretty shitty response especially to a dev who actually puts out a decent product. Unfortunate really, but guess its just the reality of things in this space ultimately.
