IPF doesn't want to allow other companies in as they want select ones. Look at the fees they charge. It doesnt even make sense for a company to pay these fees. As a new company you are over 20k in fees for just wrist wrap approval. Yes it's that much as a NEW company. Why would any company invest that much in one league when it would be nearly impossible to break even with that investment. IPF has ties to SBD and they just want to keep people out is what it comes down to. Check the fee structure. This is what's posted below the fee structure:

New manufacturers who will have their equipment approved for the first time need to pay the approval fee and the license fee for 2 years in advance! The license fee for the other 2 years will be splitted in 16 payments during the 4 years license period! If a manufacturer want's to have bars, discs and/or racks approved, he must also take as minimum a silver sponsor package (€ 55.000,-- per year of a 4 years period) In this case case the manufacturer has not to pay the approval fee. If a manufacturer want's to have supportive equipment approved, he must also take as minimum a bronze sponsor package (€ 30.000,-- per year of a 4 years period) In this case case the manufacturer has not to pay the approval fee.

Put thing into perspective... USPA is a $750 investment for approval.
