WTF is the lemon? The athletes can go. Those who medal will have no asterisks by their names. They get to be Olympians, which is what they've been training for their whole lives.
The lemon is that they are being 'allowed' to compete, but unlike their opponents, they will not be allowed to their country's uniform, hear their anthem, see their own flag go up. That is a big disappointment for the innocent athletes who did nothing wrong.
Also there is no certainty that they will get to go. There is nothing official from Russia saying one way or the other.
One more thing - The IOC is going to decide who gets to go. We have already seen how WADA had manipulated who gets to go to worlds. I don't trust them.
