I don’t get your point. Almost any software is available for download somewhere. And even if not from the distributor, where is the difference between downloading it from the distributor/developer and applying a ripped serial/registration or downloading it from a torrent and do the absolutely same thing? There IS no difference.
You wonder, why it’s not shared that often? You think, because it’s affordable? I already said, people even share stuff that costs less than $10. Renoise simply isn’t shared that often, because there are not enough dumbasses willing to spread their own name all over the net, related to copyright violation. For each new version a new dumbass would have to be nuts enough. That’s actually not hard to understand. 1+1=2
What’s got this all to do with trust? Absolutely nothing. I don’t get at all, what you’re trying to say with your whole posting, which - to be honest - sounds just pretty weird to me. Sorry.
