You're right, Cadbury chocolate isn't what it was, it tastes awful. The profit over everything else mentality took over along with the treatment of the factory and its workers at Keynham in particular, this was abysmal.
I, for one, refuse to buy Cadbury chocolate anymore and, where I'm aware, I avoid all products from the mother company.
Too many companies, like Cadbury's, have gone down the same route where their philanthropic origins with small profits have been wiped out in exchange for massive profits and bugger the workforce and the quality!
Next time you donate to a food bank think about the company owner on holiday abroad he doesn't have to worry about his workers on zero hour contracts because we are helping to feed them and keep his company profits high.
