This video is also interesting, as mumble rap also produced the e-collab producers which in return made most beats sound the same and kinda killed diversity.
I can recall 808 mafia, Sony Digital, Metro Boomin, and Zaytoven kinda starting the e-collab movement but was fully picked up by producer groups like internet money
808 Mafia was actually a production group
Southside, Lex Luger and Sonny Digital. Then like you said…Metro and Zay played they part as well
