And thats just because its easier to produce those bootlegs/remixes and let them sound good than producing your completely own track. Also with this bootlegs/remixes you more easily pull the attention of the listener who scrolls down the tracklist because he most likely knows the original and the barrier to like a track gets smaller when you know the basis of a track. (I'm only talking about the majority of the hardstyle listeners - those who don't listen to hardstyle on a regular basis)
Thats my opinion why this idea of bootlegging/remixing works out.
But I also think this is just a trend and might end sooner or later. Because sooner or later those remixes/bootleg won't appeal special anymore when you read the track tags.
