To be fair to them, selling scurrilous stories has been their most viable income stream to date.
The Netflix docu in which they 'called out' the evil, racist and colonialist RF was a huge hit (OK, it turned out not to have much replay value, but NF's KPIs related to new subs, and that docu brought in a fair few). The other programmes they've done haven't done anywhere near as well. Spotify was a disaster.
Their best income stream is RF gossip and, in a commercial sense alone, I don't blame them for doing everything they can to maximise it. The problem is that the RF have clearly taken steps to cut off that source of gossip.
If Meghan's influencing career doesn't pay, she and Harry are going to have to invent remember a few more of those terrible racist microaggressions to pay the bills.
That's if Dr C's promised account of racist macroaggressions doesn't hit them first, that is. Telling a tale of woe about the time Kate wouldn't let you use her lip gloss will tend to pale into comparison with some juicy and well evidenced accusations of real harrassment, bullying, racism and misogyny.
