Redleg – perhaps you are not aware of the way the current online marketplace works. You mention Bezos as an online seller, but in fact Amazon is a ‘marketplace’ (almost like eBay) where only part of the products are actually being sold by Amazon itself. A huge part of the items sold are either sold and shipped by private sellers, or owned and listed by private sellers but stored and shipped from an Amazon warehouse (called FBA – Fulfilled By Amazon.)
Years ago frum people discovered that selling on Amazon through an FBA business is a clean and easy (Kal V’Naki) way to make a living. There are thousands of Frum people in Lakewood and across the country that are doing it. Many Jews also sell on eBay. So although Jeff Bezos is not a Frum Jew, there is a very good chance that a product you buy on Amazon or eBay belongs to a Frum Jew.
