Some truth? Haha.
Riding on gravel or enduro is not in the slightest to be compared to CX. With some basic skills, anybody can start riding on gravel recreationally. This is completely different for a competitive sport like CX which is riding the same laps every time and in that sense not very imaginative for a recreational rider. It is a competitive sport that is not about the scenery, or about "feeling free" or the feeling you're making an epic trip. Those sports are accessible, CX is too hard and repetitive to attract a large practicing userbase which seems to be key in countries like the US. They tried getting CX, even with the silly and demeaning "stripdancer money grab" gimmick to work in the US, it simply didn't work.
If the sport were to be made Olympic, you would get athletes from around the world again, especially now with Wout and Mathieu. And it has very little to do with "thinking what people like in Flanders" when it comes to track design. Unless you are talking about completely ripping the essence of what makes CX out, dumb it down, so that every Mary *** & Jane can also start riding CX. So yes, MTB becoming an Olympic sport has been a huge burden on CX, with a lot of professional athletes migrating to a suddenly more recognized sport, which shares many traits from a competitive point of view.
