This has always been the case - do you have any idea how many forgotten Fig Faddy Fanes dropped terrible records in 1989? Young artists need to start somewhere and usually that means mimicking someone they admire. In of itself this does not bother me, it’s natural.
The problem as I see today is that the the industry, the media and, most frustratingly, a significant chunk of the audience seems more permissive of this sort of thing than in the past. Biting isn’t just allowed, it’s actively encouraged. Kids get publicity and fans and deals without anyone ever pressing them in a way that would force them to form an original thought. Then more biters bite those biters and rap just becomes this boring circle of teeth marks on top of teeth marks on top of the eight thousand fake ASAP and Keef songs that land in my inbox daily.
