Federal lawmakers backing a new bill introduced in the Senate say they want there to be more online shopping options for consumers. However, a close review of their proposal shows their draft legislation may only strengthen entrenched brick-and-mortar stores while weakening the biggest online marketplace in the world, possibly making shopping worse for consumers overall.The American Innovation and Choice Online Act has been circling Congress for years and was recently reintroduced in slightly tweaked form. Originally, the legislation was borne out of allegations that Big Tech was “self-preferencing” certain products.The bill targets so-called “systemically important” platforms with average annual gross revenues of at least $175 billion, banning target firms from self-promoting private-label brand products, such as batteries or clothing; misusing nonpublic business-user data against small businesses; and limiting competitor access to platform features. The Justice Department, Federal Trade Commission, and state attorneys general can civilly sue companies to enforce the rules. The bill looks like a direct assault on Amazon, in particular, though some critics say it could also affect Walmart, at least theoretically.
