You answered your own questions and highlighted the decrepency. Pick up the tax tab, Apple. Pick up the running costs, Apple.
FACT is that customers are making the purchase, it is the customer's sale being directed to charity (it's not a contribution from Apple), BUT even still, Apple is retaining a portion of that charitable purchase. The customer's expectation is that the whole purchase is to go to charity, directly to the victims, not a slush fund.
Fair and reasonable individuals would expect Apple to direct the COMPLETE TOTAL OF SALES, NOT A PORTION. Apple sits on billions and can't even get charity right. What Apple is doing is not charity.
Total scum corporate culture at Apple. Disgusting executives.
I think you are wrong. Apple have stated that 100% of Apple's share is going to charity. 17p is going to the government (VAT is a sales tax, not corporate tax of the kind Apple can avoid). The remaining amount you'd presumably have to ask Simco, the record label about, but given that the project was instigated by Simon Cowell precisely to help out, and he has reportedly also personally given a further £100,000 himself, so I doubt they are hanging on to any profit either.
No customer in the UK expects VAT to not go the government, unless there is a gift aid form to fill in. If Apple or Simco are taking running costs then that isn't profit, hence not profiteering.
You seem to want to be angry at Apple despite the evidence they haven't actually done anything bad here.
