None of the images on that landing page can be achieved with only a moderately priced pro-am camera. I understand your point, but Getty's model has not been disrupted and in fact they have no real competition. Getty offers professional images in a stock-like pricing model, short of agencies like AP there is no direct competition to them.
Lets go one by one on the photos on that landing page in terms of minimum equipment and people behind them... short obviously of a camera and an achieved photographer, that is already hard enough to come by and expensive but is a common factor in all images.
Katana image: model, make up, big room with stupidly expensive lamps, costume, katana, watermelon, more than one 1k/2k+ flash head.
War image: ticket to war zone, bulletproof vest, AK-47, missile launcher, missile, model/combatant. Very likely many pro camera bodies, pro to resist dust, many to have spares. You won't find a pro body there if one breaks up, unless you can loot a dead photographer.
London image: helicopter, helicopter pilot, weather controlling machine (can be replaced by an insane amount of luck or many tries and a lot of time in each one).
Guy with car hat: model, car hat, not sure if only one flash head or camera mounted strobe. I'm not sure of how much a car hat costs but I think this is the cheapest photo of the lot.
