When you are talking about Too $hort, Eazy and Dre, you’re talking about people who did their thing and the mainstream followed them. So if anything, you could say they helped make hiphop mainstream but they didn’t change what they were doing to be mainstream. Don’t get it twisted.
While I’m not a fan of the hyphy s**t, that is still a subset of hiphop that came out of Oakland. Just because it got popular in mainstream culture again, just shows that the mainstream pop culture was starting to follow hiphop, street culture. Too $hort is the OG of Oakland hiphop and a pioneer across the board for hiphop in general so he can do whatever the f**k he wants and will always be more hiphop than any of his haters. FWIW, I can enjoy hearing Too $hort to this day but I haven’t bought any of his albums since the early 90s.
