In the case of "BMF", it's a combination of things. On one hand, you've got Lex Luger expanding the formula he did with "Hard In Da Paint", except you have a rapper who's already had hit records, so people are more likely to put his single on radio.
On another hand, Ross has been developing this new gimmick thing where he starts screaming shit. After two albums of doing this mellow taunting thing, it's weird to see him suddenly acting like he's got something important to say. The big turn around was probably this record; (Which also has a Wayne verse that defends his hype to a marginal degree).

I'm just saying, Ross pulling off his shades and hissing "LOOK INTO MY EYES, DO YOU SEE A C.O.!?!?" might've been the best line all year. More because his eyes are hideous than any greatness of the lyrics.
As far as how 'real hip-hop' people like Ross... He's been around in some form or another for 10 years or so (his first appearance is actually on a Erick Sermon album under the name Teflon), and when he didn't do a song like "BMF" on his last album, it was all this lushly produced, live instruments, 'soulful' stuff... Lot of Justice League.
Also; Cocaine Blunts isn't a 'pure' hip-hop blog. Noz tends to study trends/sub-movements in hip-hop. The guy collected like every "Crank Dat..." record in a mix once. I think he sees the importance of Ross jacking Waka's vibe and running with it in a commercial fashion.
Styles P's presence on that record is irrelevant. So far not ONE New Yorker can figure out what to do on a Lex Luger beat.
