BRAND AUTHORIZATION QUESTION

I’ve been selling for a year, steadily growing month over month, with a significant spike in December, primarily through FBA private label. However, I struggle to understand how so many “wholesale” sellers manage to secure brand authorization. Take this listing below as an example. Did all 14 sellers genuinely receive approval from Chore Boy? It just doesn’t seem practical that every one of them went through the formal Amazon approval process to sell this product. I am seeking insight on whats practical here. https://www.amazon.com/Chore-Boy-811435002145-Scouring-Scrubber/dp/B007VGICGK/ref=sr_1_15?dib=eyJ2IjoiMSJ9.WG8nLqr1pPwYfgj9GB8U8G4qjRXX3C95hGo1PxZfdIEBErwfvl7C5g1756ioBuuCZL9VmFLUhMiRupWBYFANVcoKj_QLDNcgnhYXY9b-YkzN8yf4lKJPxjp3xkrugkP_LZbG6–wvUA5OqVBlROYcv51lYq7_Z9Cu95AhE2NptQm645dtawA2Byy-QVcqrxivDTkG3_ZH1TFuh0ApxbaumWW6tvkljvPO5g-pO8sGa0.tMBXRcPbJLKf6okJwI6xqZDAtc_2XdDXjd_2BMl_teE&dib_tag=se&m=A1AU249DNT5JW&marketplaceID=ATVPDKIKX0DER&qid=1740552310&s=merchant-items&sr=1-15
