Ah, I misunderstood. In fact, McGregor didn't hold up the FW division at all, ever. He earned his title shot there fair and square and then moved on. I think he could have been stripped of that title slightly earlier, but the only difference was that Aldo was for a brief period the interim champ rather than the undisputed champ. Given that the world had just watched him be easily knocked unconscious, it didn't matter what one called his title.
I don't know if you are aware, but the silly name calling makes your comments hard to take seriously, if indeed you mean to be taken seriously. I mean feel free to carry on, but it undercuts your position by making you seem petty. Canner, Mcgagger, etc. The same is true of people incessantly calling him GOAT.
However, if you be objective for a moment, you'll recall that McGregor wanted to fight RDA, who was by no means the weakest champ in recent memory (Neither was Eddie for that matter; he's underrated but is an easy match up for McGregor.) It wasn't McGregor's fault RDA pulled out of the fight.
In fat, this is one of the criticisms I'd level at McGregor's critics. They hold him accountable for fighting Mendes and Nate, and Alvarez, but in fact he himself had been aiming at other fighters who pulled out of their fights. One of the reasons for McGregor's sustained popularity is his understanding that the show must go on. He's always been all about saving cards.
I see the principle in saying he should have been stripped as soon as the Mayweather fight was booked, but it's nonsensical to think it would have ever happened. The UFC's mistake was in not forcing him to book a fight soon after and using the threat of stripping him as leverage in October or November.
McGregor has gotten rather less preferential treatment than his critics often claim, but for sure he got plenty. He often did much more for the UFC than almost any other fighter, including taking high risk last minute replacements in more than one fight (something guys like Jon Jones and Werdum refused to do) and also putting in many more hours of media work than most other fighters. But frankly, with Sherdog clamoring so often for fighters to have more leverage against the evil UFC empire, it strikes me as strange that people then complain so bitterly when he wrings concession after concession out of Dana White.
The fact that he was taking fights outside of the division instead of either defending his belt or vacating did in fact clog up fw because edgar never got a title shot vs mcgregor, instead he had to fight the person who most people agree is his worst possible match-up, ruining his chances of becoming fw champion for the next two years.
Silly name calling is part of sherdog culture; if you can't look past that and simply focus on the message/content, I wonder how you survive a single day here; perhaps that's part of the reason why you confuse "hate" with serious criticism which is levied based on events that have transpired due to a pampered champion who's been fast-tracked and coddled through his entire tenure with the organization.
I do in fact recall mcgregor getting a gifted title shot at lw vs the incumbent champion at the time, dos anjos, a fight many people believed would end poorly for the newly crowned fw champion; hafael had been looking unbeatable after demolishing diaz, cerrone, henderson, and pettis in short order. The reason why the match was drawing so much ire though is because conor had just won the fw belt, had not made a single defence, and he's immediately getting a title shot at a higher weight class? Absurd, and another example of the favouritism displayed towards him.
When given the option of who to replace rda (i.e. handpicking his opponent, like he did with out of camp/out of shape mendes), he decided to pick nate, who was on vacation in cabo, taking shots of tequila when he got the call (allegedly). Despite having the advantage of going through a full camp, and not having to cut as much weight to get all the way down to 11 stone, he still lost the match and was given a rematch right away; who else has gotten an immediate rematch after being stopped in the second round, especially in a fight that was meaningless to begin with?
And while mcgregor deserves credit for not asking to be pulled off of cards (with the exception of 200, where he almost forced the ufc to take him off the card by failing to meet his contractual media obligations), many people go overboard acting like he was at a horrible disadvantage by facing guys who weren't even training for a fight prior to getting a 2-4 week notice to face him. I'm not really sure why you lumped the fight vs alvarez in there though; he didn't "save" that card and it certainly wasn't short notice or anything, it was a gift to him (once again) after going 1-1 vs a perennial gatekeeper.
Obviously the ufc was letting him keep the belt as a prop, however that doesn't change the fact that they were doing a disservice to the rest of the fighters in that division for the sake of mcgregor, and it makes one wonder why he's still been allowed to hold onto the status as champion for this long.
