Where did you see they did “put black artists out of the way” …? There were much more back artists in the pop charts in the late 60s and 70s compared to the 50s and early 60s. And the Beatles, The Rolling Stones, Clapton, Mayall and all greatly helped in that direction by introducing that music to a larger audience and helped break the barriers between segregated audiences.

Regarding the R&B charts it was stopped late 63 because there was a disconnection with its initial target (yes mostly black people at the time): there were too many white artists in it due to the way music was labeled R&B (this was BEFORE British Invasion and Beatles on the Ed Sullivan show) and Billboard decided to stop it and revived it only early 65 with a revised formula intended to target more black artists. Beatles chart success had nothing to do with it from what I’ve read. And artists could be present on BOTH pop and R&B charts.

Seems to me you are rewriting history to support your argumentation. 🤔
