Not likely, he definitely did. Even on YT.
I remember on YT a couple years ago when Drake dropped track with Future, that YT permanently put on my suggestions on the side. At the top too, for like a month. Keep in min, I purposely dont log into YT and will be in private browsing so I can reset the algorithm when I want to.
Multiple times over that month, I wouldnt even be watching music videos, or when I was listening to music, it wasnt even rap. It will be a bunch of suggestions that go along with what I was viewing(car vids/travel vids) and listening to(reggae/90s alternative/EDM/Jazz) & randomly Drake & Futures new release. They werent even hiding the obvious paid roll out.
I never experienced that shit once during the whole Kendrick beef. Like everyone else that said it, we don't wanna hear you pretend like your going against the machine for everyone, when its clearly because you felt you don't get your way. I dont think I ever seen Drake stand up for anything his entire career.
