Its kind of like them kids that sit in a corner and go 20-2 in cod, they think that they are really good but in reality they're doing it in a way that they can't lose. Fly out is fine for messing around or getting a certain motion nailed, just don't whore I all day.
Excellent analogy
To add on to that, flyout is hated because it's so unnatural and doesn't look good. You're getting as much air possible given assistance of a quarter/bank (what have you) then landing totally flat. You know, it's exactly like matr said about obtaining a 20-2 score in cod. It's like "Well I can do it, I just need all these special circumstances, meanwhile, they are all the circumstances that make it easier and make my style look worse." It's like you don't even know how to truly do the trick if you can only do it flyout. It's not fun to watch a kid hammering out his trick list on a string of single trick clips done by being launched 8 feet into the air and then coming back down. It's like, you need a ramp for assistance to do the trick, but you're not going to use any other part of the park to flow around and look good, it just looks like you're just trying to get the job done the easiest way possible.
There's nothing wrong with it. It's a useful tool in learning things and in some cases, is one of the only way to land some insane things (such as the Ryan Williams mention earlier-would you expect him to do that over a spine?) and it's definitely a way to have fun which is obviously the most important factor. However, if you're shooting a vid, probably part of the reason is for entertainment purposes and the "cosmetically appealing factor behind your style and tricks, how they're done and how they're executed. Flyout is not a nice way to display those things. Put simply, it's not fun to watch. Anything past that is clueless kids forgetting why people don't like watching flyout to start with and see it as a new hate trend, which happens allll the time, especially in this type of community with the age group that falls in it.
It doesn't look like you're riding your scooter, just trying to land some trick, and really that's exactly what it is
