About a dozen US senators from both parties on Monday formally introduced a bill that would bar Big Tech platforms, like Amazon and Alphabet's Google, from favoring their products and services.

Senators Amy Klobuchar and Chuck Grassley's bill would prohibit platforms from requiring companies operating on their sites to purchase the platform's goods or services and ban them from biasing search results to favor the platform.
A companion has passed the House Judiciary Committee. It must pass both houses of Congress to become law.
Amazon said in a statement that the bill, if it became law, "would harm consumers and the more than 500,000 US small and medium-sized businesses that sell in the Amazon store, and it would put at risk the more than 1 million jobs created by those businesses."
Google said that the measure would make it more difficult for companies to offer free services − Google's search and maps are both free − and would make "those services less safe, less private and less secure."
Companies expressing support for the bill included Spotify, Roku, Match Group and DuckDuckGo, Klobuchar's office said in a statement.
