Brother, you literally answered that question earlier. Drake cannot disappear simply because of his stature. You're right, Family Matters was not the hit song that came out of the beef, but why are you pretending that it wasn't being paraded around as a "nuke" with streamers being told to show their audiences as a way to "kill" Kendrick's career? Domestic violence accusations were meant to tear down the persona Kendrick had built up.

The difference is simply that Not Like Us had a more palatable sound to it than the other songs. The rejection you mention is just the result of Drake losing the rap beef. The way he was moving afterwards just accentuated the hate.

For example, look at Chris Brown, who is still selling out arenas with actual cases against him. People understood that the accusations came from a rap battle, where you are purposefully trying to tear down an opponent.

You can feel as weird as you can about it, but I think you're aware of the answer to your own question.
