"The Big Top 40 show on Capital FM and Heart opted not to play the song"
But in this case it's not the BBC refusing to play it... is it? I'm not too familiar with British radio stations, so those might well be BBC's subsidiaries.
Anyway, "this is quite natural" - I don't think the criticism was that it's unnatural, just ethically suspect.
Capital and Heart are privately owned and operated stations. The BBC Charts usually air on Radio 1 I think on Friday, so we will have to see if they opt to play it then, though I strongly suspect they will not.
