Top private schools losing their grip on Oxbridge article

[Nevermakeit]

Interesting article from the FT today . I don't understand why there never seems to be any nuance separating the top private schools which are incredibly hard to get into, and therefore select very bright children, and the more mediocre ones where the main discriminator is the ability to pay the fees...
If I were head of one of the top schools (and not just a parent!), this is what I would be arguing, that the children are not simply hothoused (though of course they undoubtedly are), but they were exceptional to begin with!! Yet, they never seem to put this across (either in the media or to the Oxbridge colleges themselves, where they supposedly have such great relationships), and agree to be lumped together with all the other private schools.
I just don't understand it, especially as then they could get their kids in more 'under the radar' , as at the national level, the state school intake would still be looking good....
What do others think?

Yep contextual offers at Oxbridge are a myth.
Good friend whose children went to Guildford boys and girls told me with absolute certainty that my DC would get contextual offers. Eh? I said. Oh yes she said. Our children were told this in their Oxbridge presentation - that they'd be up against pupils from state schools with contextual
Offers.
No!
It's a myth spun to belittle the achievements of the comp kids
