From everything we know so far, the two situations are totally different. Powerful elements were trying to distort what happened with CF and destroy her (immediate sacking by ITV, constant misinformation by the tabloids, labels of her being a domestic abuser, a photo sinisterly sold (by who?) to the papers showing blood on their bed, with the accompanying lie that it was her bf's blood when it was in fact her own blood, police giving salacious / misleading quotes, no urgent help given to her when she was in fact the one who was vulnerable on the night in question etc etc).
With PS the mounting evidence shows there is something that should be investigated (potentially by police, certainly by his employers) and yet instead, all the stops have been pulled out to cover this up and silence everyone and protect him. Media being allegedly gagged, PR consultancy allegedly doing damage limitation to the tune of £30K a week, full support of his employers, peers, and a now compliant media who never discuss PS without the 'brave' prefix. Hasn't lost any of his work or sponsorships (a new wine out with Waitrose - his rep is just fine apparently).
No comparison there, even remotely. Polar opposites in fact.
Don't forget what Katie Piper had to say too.
