They'll keep going, because they constantly think that the next interview is the one that will 'turn the tide'. It never is, and the more the say the more they contradict themselves. The more detail they add the falser the story looks. The more they escalate, the bigger the next project has to be.I just can't see what their next steps are from this. I know MM is supposed to be writing her own book now, but surely she must be very nervous now that it will tank and she might be humiliated and torn apart by the media even further than in recent weeks.
They don't really have anything new to sell after this and once the coronation is over (which remains to be seen if they attend or not at this stage) then there won't be any other events they will be required to attend as non working royals. That means not getting any new info and only being able to harp on about their short time as royals.
I really felt like they might offer a breath of fresh air when they left and really stood a chance of doing something positive, and may have even genuinely made themselves very popular against the actual working royals. But that ship really feels like it has sailed now though, and is largely of their own making in recent weeks.
All they've got to sustain themselves is shilling royal family stories. Harry's thick as two planks and as ugly as them too. Meghan has ruled herself out of acting by marrying too high up. They have huge expenses in Montecito, and their security is expensive. They'll need millions a year to keep on running.
