Not for stunting?

I work at a bike shop. There I spend a lot of time building BMX bikes, ranging from low end beginner completes, to $3000 top of the line customs.

Today I spotted this sticker on one of the bikes from a company who’s got their debut with completes this year.

I know that it’s probably the factory where it’s made and assembled who’s got some kind of policy to put these stickers on there. But seriously? Since when is a freestyle BMX bike, no matter the price, “Not for stunting”?
