NOT everyone wants to run in regionals.
And the price of the "legal" stuff is way overboard for budget club racers.
The cheaper stuff is still perfectly safe and legal and as safe as any other, as its sold that way, BRCA is only a UK thing. So lets remember the rest of the world excists! We are only a small island people!
I have used many non BRCA items and they perform perfectly at half the price.
Pay your money and take your choice. Simple really.......
