I just looked at her blog and at the posts about last year and this year, and I think you should re-read them. She didn't celebrate, she *stated* that she would get the finisher's medal during the first one. She was telling the story, and part of the story was the bus person telling her that she would get it.
And the post from the 2012 race said she was trying for the half, just like this year. There was no change.
I think you have been mis-remembering a bit.
I have a big long story that involved getting a 4th place medal for finishing 4th out of 4, but I won't bore you with it. That experience is what makes me 100% OK with starters getting finishers medals, even though my story didn't end with "and then I took that medal and proved that I could win" etc etc, because I previously had had winning experiences, and the (non-running) race where 4th out of 4 happened also happened to be the last scheduled race of my rowing career. There was nowhere to go with it because there WAS nowhere to go with it. (the other women on my team, however, had another year of eligibility and DID get to do amazing things during their last year)
Apart from randomly hearing people pre-brag on the way to corrals, I'm a little nervous while reading this thread about the criteria people are using to decide who should and who should not get finishers medals when they didn't finish. I'm definitely sure that Disney has NO interest in deciding this. They are trying to be NICE. To give a medal to someone who broke their leg in the last mile is just as nice as to give it to someone who went only 2 miles. If I'm fine with one, I'm fine with the other. But I'd prefer to not be trying to judge that in the first place.
Even though I'm a "baby" adult-runner, I ran all my younger life. I ran for the love of running. I ran because my malamute needed to be run to keep him happy (he would have preferred I put a sled on him and take him to Alaska, but that wasn't possible). I ran and ran and ran and at NO point during my runs did I ever feel bad because someone else was, or wasn't, running.
Right now I'm still a treadmill runner looking to a future of running on the ground and doing more than the
Castaway Cay 5K. I am still getting down to an excellent weight and retraining my joints that they actually can stay together without the fat-glue they had in them for several years. I'm still new at this, as an adult out of college, anyway.
But when I'm on the treadmill at the end of a run, and my end-of-run songs come on my mp3 player (when I'm listening to it...I find I do better without the music during the bulk of my runs), and I find a little extra lift because I love hearing Gwen Stefani, I start smiling. I'm a weirdo on a treadmill smiling and sometimes laughing because finishing that run feels SO good (even when it hurts).
And I cannot imagine a time when someone else getting a medal that I feel they don't "deserve" will negatively affect my life at all, will take that "omg I'm FLYING" smile off my face. I can't even imagine getting to a point where I would sit down and come up with a list of reasons for why I might deserve it but someone else doesn't.
I get *that* it bugs people; I just can't figure out *why*.
