Froome breaking through at 26 = fraud
Nieve, Lopez, Kiry breaking through at 26 = always been good
Kiry's breakthrough came when he won a bunch of Italian .2 races in 2005, when he was 23-24. He started 2006 in similar form and got a ProConti ride where he built on his results before getting the Tinkoff ride in 2007.
López and Nieve did improve at 25-26 like Froome, but there is a difference in the scale of the improvements; López also did not sustain that level, and only in 2011 when Movistar gave him a lot more freedom due to the many disasters that befell them did he look like achieving that kind of level again. He's matched that level since joining Sky, but while being about eleventh in the hierarchy, which is impressive. Nieve broke out fairly late, but with all his best performances being late on in GTs that seems to be an issue of recovery more than anything else. Either way, he hasn't performed appreciably better at Sky than before.
The other thing is, Froome was performing at a level around the same as these guys until 26, but a breakout that sees you make it to 6th in Paris-Nice and 3rd in the Deutschlandtour, or a breakout that sees you finish 12th in the Vuelta (later promoted after García's DQ) and win a stage from the breakaway after your team leader crashes out of the race and the team's stage plan is all about you getting there, is nothing like the same as a breakout that sees a rider coming from that kind of level and winding up indisputably the best rider in the world, demolishing mountains and time trials despite lacking technique, and not breaking out with tactical masterstrokes (Euskaltel's mountain TTT to get the win on Cotobello for example) but with the exact opposite; power in abundance that he had never had before that allow him to win despite appalling tactical racing. They didn't suddenly go from losing 8 minutes on an intermediate stage in Poland to demolishing GT winners on steep mountains and losing GTs on bonus seconds within two weeks.
That's why López, Kiry and Nieve are given more of a free pass than Froome. It really isn't that difficult. If Froome had progressed from 2009 to 2011 his improvement would still have been surprising but people wouldn't be as quick to condemn; and if Froome in 2011 had improved to the fringes of the top 10 and then continued to improve to the point where he now dominates people wouldn't be as quick to condemn either (and the bilharzia story that's as riddled with inconsistencies as Froome was riddled with worms might be more readily accepted). But Froome's transformation was so preposterously sudden it was like a ten year old who can't get past a level on a computer game suddenly enabling God Mode.
