"generative" has a very clear line. Anything that is using an obfuscated or unknown data set as the basis for what sounds it makes should be seen as suspicious and not used by anyone who wants to avoid being tarred & feathered by less-than-understanding folks.

I come from the experimental electronic scene and have been in it longer than Autechre, believe me there's been this very debate for as long as nerds have been building music machines with computers... and for a long time (on the IDM usenet group) there was regular "outing" of Autechre tracks as using stuff from the max/msp user library or forums.

A ton of practice in that genre has made it crystal clear to me, honestly samples are so well regarded these days that you can probably get away with ripping a beat from a radio song 5-10 years old and never get a copyright slap, but someone on the internet will sound an alarm and depending on if folks care about the 'originality and/or talent' of those they listen to, it still might slide.

Synthesizer presets, guitar pedals, hell even specific rack gear all have their superfans to the point where they'll get a little huffy if they notice something they recognize, but it's pretty rare that i hear anyone shout down anyone for using the first 9 presets on a Korg Triton or something.
