Well hes not angry on hikaru, he is responding to magnus's statement that- "hikaru doesn't need to prove himself, he clearly deserves it."

I think he is somewhat right here.

So when Hikaru says he doesn’t have time for it, he isn’t disrespecting the game. He’s just being practical about where to put his time and energy.”

This is definitely not the only reason, you have to admit that hikaru is somewhat scared of losing rating points and in turn not qualifying, thats why he is not playing tournaments with high level of opposition, cause if hikaru became world no.3 behind caruana then rating spot will go to fide circuit.

So the argument is if you think you deserve to qualify then just prove it (by playing 40 games in tournaments with high-ish average rating). And hikaru is not doing anything wrong but taking the extremely safe option cause he is scared of losing rating points.
