Replying to Freeskiing, Freeriding, Park-skiing

Okay, I might be wrong and if I am, I would be glad to get this clear in my head.

So to me, Freeskiing is the word to define every thing between Park skiing and big mountain.

Freeriding is big mountain, freeriding = Cattabriga.

Freestyle is park skiing, urban and we could include backcountry.

Freeskiing... not many are actual freeskiers, I think of Candide, JF Cusson, JP Auclair, the list is long but that's my point.

Am I wrong somewhere ? Are those meaning subjective somehow ?
