"I don't own a computer, but I do have a fridge. I demand that iPlayer will work on that. And on my sofa. And while we're at it, I drive a Vauxhall Astra, and I demand that the East Coast main line electric power system be modified so that it becomes compatible to MY vehicle of choice. I shop at Tesco, but Sainsbury's don't give me loyalty points - that's fundamentally wrong too. And why are lottery wins only paid out to people who've bought the right ticket? Bleat! Baaaa! Bleat!!!"
Reality check, going with alternatives would allow it to run on ALL computers capable of media playback, not just provide an additional alternative for those who use 'fringe' computing devices. Inconveniencing no one, lowering costs, and improving compatibility across the board.
Further more, due to the way the BBC is licensed here, WE ARE PAYING FOR THIS SERVICE, so it'd be quite nice for it to work properly, no?
Errata: If you don't own a computer, you at least have access to one, otherwise you wouldn't be reading el reg.
Your car is compatible with roads which follow the same general route as the rail line, so at least you can still get where you are going.
If you shop at tesco, take out a tesco reward card - you have that option.
And as for the lottery, if everyone won it, you'd get less than a quid back for your winning lottery numbers.
