Yes, he kept the belt for a year. But he kept talking about fighting for the LW title, first against RDA, then against Alvarez. In that year, Aldo was offered a rematch but I don't think he was owed one.
I an understand the complaint that he should have been stripped earlier, but I don't see how he owed Aldo anything. He was fighting at LW, and when Aldo was offered a LW bout at the last minute, he refused.
Common sense is always defined as agreeing with the one talking abut common sense. My sense of this whole affair is that half the fans ccriticize Aldo rightfully and the other half criticize McGregor rightfully. Few are interested in doing both. It was ridiculous for McGregor to hold onto the belt when he had no intention of returning to FW, but when you KO the FW GOAT, you're going to get away with it.
But Aldo and his fans have displayed a baseless sense of entitlement. This is why I took exception to your claim (or whoever it was) that McGregor owed Aldo a fight. That's bull. It was on Aldo to chase that fight, not on McGregor to hand it to him.
