The reaction has been strongest among athletes and spectators; and it is the athletes who are speaking out, invoking the idea that politics are playing a role in determining who competes and who doesn't. "It's like FINA keep going back on their word, and the IOC keep going back on their word," Irish swimmer Fiona Doyle told reporters. "And FINA caved in to [Russian President Vladimir] Putin, and that's just not fair on the rest of the athletes who are clean. Who are you supposed to trust now? They have signs all over the village saying we are a clean sport - and it's not."
